Fix up some Content-Type handling in account/container listings

Update content type on 204 (not just 200) to properly handle HEAD
requests from xml/txt listings.

    Add "Vary: Accept" header to listings, since otherwise, browsers may
    serve the wrong content type from cache (even though we *would have*
    sent the *right* type if it actually sent the request).

Delay importing swiftclient until after monkey-patching

Commit message below partly copied from nova:

Eventlet monkey patching should be as early as possible

    We were seeing infinite recursion opening an ssl socket when running
    various combinations of python3, eventlet, and urllib3. It is not
    clear exactly what combination of versions are affected, but for
    background there is an example of this issue documented here:

https://github.com/eventlet/eventlet/issues/371

    The immediate cause in swift's case was that we were calling
    eventlet.monkey_patch() after importing swiftclient (which imported
    requests, which finally imported urllib3).

    We only use the imported function in one place, however; hold off on
    importing until we actually need it to ensure that monkey patching
    happens first. Note that we *don't* want to monkey-patch at import time,
    as we've previously had bugs related to import-time side-effects.

Remove reno from test-requirements
    
    Reno is only needed for building release notes. Reno has now dropped py2
    support, so attempts to install all requirements for py27 jobs fail with
    the latest reno release.
    
    Reno is already correctly listed in doc/requirements.txt, so this just
    removes the unnecessary entry in test-requirements.txt.

    middleware will change the manifest returned from object server.

Middleware that allows a user to have quoted Etags
    
    Users have complained for a while that Swift's ETags don't match the
    expected RFC formats. We've resisted fixing this for just as long,
    worrying that the fix would break innumerable clients that expect the
    value to be a hex-encoded MD5 digest and *nothing else*.
    
    But, users keep asking for it, and some consumers (including some CDNs)
    break if we *don't* have quoted etags -- so, let's make it an option.
    
    With this middleware, Swift users can set metadata per-account or even
    per-container to explicitly request RFC compliant etags or not. Swift
    operators also get an option to change the default behavior
    cluster-wide; it defaults to the old, non-compliant format.

Add unittest2 back to lower-constraints.txt

      * we bump up our minimum-supported version of testtools to a version

New Object Versioning mode
    
    This patch adds a new object versioning mode. This new mode provides
    a new set of APIs for users to interact with older versions of an
    object. It also changes the naming scheme of older versions and adds
    a version-id to each object.
    
    This new mode is not backwards compatible or interchangeable with the
    other two modes (i.e., stack and history), especially due to the changes
    in the namimg scheme of older versions. This new mode will also serve
    as a foundation for adding S3 versioning compatibility in the s3api
    middleware.
    
    Note that this does not (yet) support using a versioned container as
    a source in container-sync. Container sync should be enhanced to sync
    previous versions of objects.

container-sync: Sync static links similar to how we sync SLOs
    
    This allows static symlinks to be synced before their target. Dynamic
    symlinks could already be synced even if target object has not been
    synced, but static links previously required that target object existed
    before it can be PUT. Now, have container_sync middleware plumb in an
    override like it does for SLO.

Stop retrying every deletes in container-sync
    
    Internal clients used to retry operations even on client errors, where
    we had no expectation that we would get a different response. Among
    other things, this would cause container-sync to needlessly retry
    deletes that would 404, even though we had code specifically in place to
    say that 404s are OK.
    
    While we're at it, also flag 409s as being OK (since the remote has
    newer data than us).

Import directly from the inside of the ring module
    
    An odd thing happened: when my code did only
    "from swift.common.ring import Ring", and nothing else,
    the interpreter looped on the CPU.
    
    The import from the top of the ring module is our standard
    protocol for Ring. It causes no problem in places like
    container updater or list_endpoints.py. It is a big
    mystery why it causes Python 3.7.3 to loop, and only
    in specific circumstances.
    
    But we noticed that the recursive import is unnecesasry
    in this case, so an obviously harmless fix exists.

sharding: Better-handle newlines in container names
    
    Previously, if you were on Python 2.7.10+ [0], such a newline would cause the
    sharder to fail, complaining about invalid header values when trying to create
    the shard containers. On older versions of Python, it would most likely cause a
    parsing error in the container-server that was trying to handle the PUT.
    
    Now, quote all places that we pass around container paths. This includes:
    
      * The X-Container-Sysmeta-Shard-(Quoted-)Root sent when creating the (empty)
        remote shards
      * The X-Container-Sysmeta-Shard-(Quoted-)Root included when initializing the
        local handoff for cleaving
      * The X-Backend-(Quoted-)Container-Path the proxy sends to the object-server
        for container updates
      * The Location header the container-server sends to the object-updater
    
    Note that a new header was required in requests so that servers would
    know whether the value should be unquoted or not. We can get away with
    reusing Location in responses by having clients opt-in to quoting with
    a new X-Backend-Accept-Quoted-Location header.
    
    During a rolling upgrade,
    
      * old object-servers servicing requests from new proxy-servers will
        not know about the container path override and so will try to update
        the root container,
      * in general, object updates are more likely to land in the root
        container; the sharder will deal with them as misplaced objects, and
      * shard containers created by new code on servers running old code
        will think they are root containers until the server is running new
        code, too; during this time they'll fail the sharder audit and report
        stats to their account, but both of these should get cleared up upon
        upgrade.
    
    Drive-by: fix a "conainer_name" typo that prevented us from testing that
    we can shard a container with unicode in its name. Also, add more UTF8
    probe tests.

Have slo tell the object-server that it wants whole manifests
    
    Otherwise, we waste a request on some 416/206 response that won't be
    helpful.
    
    To do this, add a new X-Backend-Ignore-Range-If-Metadata-Present header
    whose value is a comma-separated list of header names. Middlewares may
    include this header to tell object-servers to send the whole object
    (rather than a 206 or 416) if *any* of the metadata are present.
    
    Have dlo and symlink use it, too; it won't save us any round-trips, but
    it should clean up some object-server logging.

py3: Make seamless reloads work
    
    Starting with Python 3.4, newly-created file descriptors are non-inheritable
    [0], which causes trouble when we try to use a pipe for IPC. Fortunately, the
    same PEP that implemented this change *also* provided a new API to mark file
    descriptors as being inheritable -- so just do that.
    
    While we're at it,
    
    * Fix up the probe tests to work on py3
    * Fix up the probe tests to work when policy-0 is erasure-coded
    * Decode the bytes read so py3 doesn't log a b'pid'
    * Log a warning if the read() is empty; something surely went wrong
      in the re-exec

s3api: Better handle 498/429 responses
    
    Currently, they just 500 as an unexpected response status. Much better
    would be S3's '503 Slow Down' response.
    
    Of course, that's all dependent on where you place ratelimit in your
    pipeline -- and we haven't really given clear guidance on that. I'm not
    actually sure you *want* ratelimit to be after s3api and auth... but if
    you *do*, let's at least handle it gracefully.

Allow internal clients to use reserved namespace
    
    Reserve the namespace starting with the NULL byte for internal
    use-cases.  Backend services will allow path names to include the NULL
    byte in urls and validate names in the reserved namespace.  Database
    services will filter all names starting with the NULL byte from
    responses unless the request includes the header:
    
        X-Backend-Allow-Reserved-Names: true
    
    The proxy server will not allow path names to include the NULL byte in
    urls unless a middlware has set the X-Backend-Allow-Reserved-Names
    header.  Middlewares can use the reserved namespace to create objects
    and containers that can not be directly manipulated by clients.  Any
    objects and bytes created in the reserved namespace will be aggregated
    to the user's account totals.
    
    When deploying internal proxys developers and operators may configure
    the gatekeeper middleware to translate the X-Allow-Reserved-Names header
    to the Backend header so they can manipulate the reserved namespace
    directly through the normal API.

Seamlessly reload servers with SIGUSR1
    
    Swift servers can now be seamlessly reloaded by sending them a SIGUSR1
    (instead of a SIGHUP).  The server forks off a synchronized child to
    wait to close the old listen socket(s) until the new server has started
    up and bound its listen socket(s).  The new server is exec'ed from the
    old one so its PID doesn't change.  This makes Systemd happier, so a
    ReloadExec= stanza can now be used.
    
    The seamless part means that incoming connections will alwyas get
    accepted either by the old server or the new one.  This eliminates
    client-perceived "downtime" during server reloads, while allowing the
    server to fully reload, re-reading configuration, becoming a fresh
    Python interpreter instance, etc.  The SO_REUSEPORT socket option has
    already been getting used, so nothing had to change there.
    
    This patch also includes a non-invasive fix for a current eventlet bug;
    see https://github.com/eventlet/eventlet/pull/590
    That bug prevents a SIGHUP "reload" from properly servicing existing
    requests before old worker processes close sockets and exit.  The
    existing probtests missed this, but the new ones, in this patch, caught
    it.
    
    New probe tests cover both old SIGHUP "reload" behavior as well as the
    new SIGUSR1 seamless reload behavior.

proxy: stop sending chunks to objects with a Queue
    
    During a PUT of an object, the proxy instanciates one Putter per
    object-server that will store data (either the full object or a
    fragment, depending on the storage policy). Each Putter is owning a
    Queue that will be used to bufferize data chunks before they are
    written to the socket connected to the object-server. The chunks are
    moved from the queue to the socket by a greenthread. There is one
    greenthread per Putter. If the client is uploading faster than the
    object-servers can manage, the Queue could grow and consume a lot of
    memory. To avoid that, the queue is bounded (default: 10). Having a
    bounded queue also allows to ensure that all object-servers will get
    the data at the same rate because if one queue is full, the
    greenthread reading from the client socket will block when trying to
    write to the queue. So the global rate is the one of the slowest
    object-server.
    
    The thing is, every operating system manages socket buffers for incoming
    and outgoing data. Concerning the send buffer, the behavior is such that
    if the buffer is full, a call to write() will block, otherwise the call
    will return immediately. It behaves a lot like the Putter's Queue,
    except that the size of the buffer is dynamic so it adapts itself to the
    speed of the receiver.
    
    Thus, managing a queue in addition to the socket send buffer is a
    duplicate queueing/buffering that provides no interest but is, as shown
    by profiling and benchmarks, very CPU costly.
    
    This patch removes the queuing mecanism. Instead, the greenthread
    reading data from the client will directly write to the socket. If an
    object-server is getting slow, the buffer will fulfill, blocking the
    reader greenthread. Benchmark shows a CPU consumption reduction of more
    than 30% will the observed rate for an upload is increasing by about
    45%.
