Bug Description

The consume_from_instance method will throw an exception if the instance has numa topology defined.
This happens because 'requests' are not retrieved from pci_requests.

If the instance has pci_requests this may not work either as apply_requests will remove pci devices from the pool so
numa_fit_instance_to_host may fail (because there are no devices left)

Fix handling of pci_requests in consume_from_instance.

    Properly retrieve requests from pci_requests in consume_from_instance.
    Without this the call to numa_fit_instance_to_host will fail because
    it expects the request list.
    And change the order in which apply_requests and numa_fit_instance_to_host
    are called. Calling apply_requests first will remove devices from pools
    and may make numa_fit_instance_to_host fail.

Add security group calls missing from latest compute rpc api version bump

The recent compute rpc api version bump missed out on the security group
related calls that are part of the api.

    One possible reason is that both compute and security group client side
    rpc api:s share a single target, which is of little value and only cause
    mistakes like this.

This change eliminates future problems like this by combining them into
one to get a 1:1 relationship between client and server api:s.

Fix migrate_flavor_data() to catch instances with no instance_extra rows

    The way the query was being performed previously, we would not see any
    instances that didn't have a row in instance_extra. This could happen if
    an instance hasn't been touched for several releases, or if the data
    set is old.

    The fix is a simple change to use outerjoin instead of join. This patch
    includes a test that ensures that instances with no instance_extra rows
    are included in the migration. If we query an instance without such a
    row, we create it before doing a save on the instance.

Add numa_node field to PciDevicePool
    
    Without this field, PciDevicePool.from_dict will treat numa_node key in
    the dict as a tag, which in turn means that the scheduler client will
    drop it when converting stats to objects before reporting.
    
    Converting it back to dicts on the scheduler side thus will not have
    access to the numa_node information which would cause any requests that
    will look for the exact match between the device and instance NUMA nodes
    in the NUMATopologyFilter to fail.

scheduler: re-calculate NUMA on consume_from_instance
    
    This patch narrows down the race window between the filter running and
    the consumption of resources from the instance after the host has been
    chosen.
    
    It does so by re-calculating the fitted NUMA topology just before consuming it
    from the chosen host. Thus we avoid any locking, but also make sure that
    the host_state is kept as up to date as possible for concurrent
    requests, as there is no opportunity for switching threads inside a
    consume_from_instance.
    
    Several things worth noting:
      * Scheduler being lock free (and thus racy) does not really affect
      resources other than PCI and NUMA topology this badly - this is due
      to complexity of said resources. In order for scheduler decesions to not
      be based on basically guessing, in case of those two we will likely need
      to introduce either locking or special heuristics.
    
      * There is a lot of repeated code between the 'consume_from_instance'
      method and the actual filters. This situation should really be fixed but
      is out of scope for this bug fix (which is about preventing valid
      requests failing because of races in the scheduler).

Fix kwargs['migration'] KeyError in @errors_out_migration decorator
    
    @errors_out_migration decorator is used in the compute manager on
    resize_instance and finish_resize methods of ComputeManager class.
    It is decorated via @utils.expects_func_args('migration') to check
    'migration' is a parameter to the decorator method, however, that
    only ensures there is a migration argument, not that it's in args or
    kwargs (either is fine for what expects_func_args checks).
    The errors_out_migration decorator can get a KeyError when checking
    kwargs['migration'] and fails to set the migration status to 'error'.
    
    This fixes the KeyError in the decorator by normalizing the args/kwargs
    list into a single dict that we can pull the migration from.

Release Import of Translations from Transifex
    
    Manual import of Translations from Transifex. This change also removes
    all po files that are less than 66 per cent translated since such
    partially translated files will not help users.
    
    This updates also recreates all pot (translation source files) to
    reflect the state of the repository.
    
    This change needs to be done manually since the automatic import does
    not handle the proposed branches and we need to sync with latest
    translations.

Use kwargs from compute v4 proxy change_instance_metadata
    
    The args were passed to the compute manager method in the wrong order.
    We noticed this in the gate with KeyError: 'uuid' in the logs because of
    the LOG.debug statement in change_instance_metadata. Just use kwargs
    like rpcapi would normally.
    
    There isn't a unit test for this since the v4 proxy code goes away in
    liberty, this is for getting it into stable/kilo.

compute: stop handling virt lifecycle events in cleanup_host()
    
    When rebooting a compute host, guest VMs can be getting shutdown
    automatically by the hypervisor and the virt driver is sending events to
    the compute manager to handle them. If the compute service is still up
    while this happens it will try to call the stop API to power off the
    instance and update the database to show the instance as stopped.
    
    When the compute service comes back up and events come in from the virt
    driver that the guest VMs are running, nova will see that the vm_state
    on the instance in the nova database is STOPPED and shut down the
    instance by calling the stop API (basically ignoring what the virt
    driver / hypervisor tells nova is the state of the guest VM).
    
    Alternatively, if the compute service shuts down after changing the
    intance task_state to 'powering-off' but before the stop API cast is
    complete, the instance can be in a strange vm_state/task_state
    combination that requires the admin to manually reset the task_state to
    recover the instance.
    
    Let's just try to avoid some of this mess by disconnecting the event
    handling when the compute service is shutting down like we do for
    neutron VIF plugging events. There could still be races here if the
    compute service is shutting down after the hypervisor (e.g. libvirtd),
    but this is at least a best attempt to do the mitigate the potential
    damage.

Forbid booting of QCOW2 images with virtual_size > root_gb
    
    Currently, it's possible to boot an instance from a QCOW2 image,
    which has virtual_size bigger than one allowed by the given flavor
    (root_gb).
    
    The issue is caused by two different problems in the code:
    
    1) typo in get_disk_size() has made it always return None and
       effectively disabled verify_base_size() checks
    
    2) Rbd image backend skips the verify_base_size() step for
       'cached' images (the one with base files), so it is possible to
       boot an instance using a larger flavor once and then use smaller
       flavors to boot the same image, even if allowed root_gb size is
       smaller than the image virtual size

Pass migrate_data to pre_live_migration
    
    Commit ebfa09fa197a1d88d1b3ab1f308232c3df7dc009 added an RPC proxy but
    as part of that was passing migrate_data=None for pre_live_migration
    which breaks live block migration when not using shared storage.

Add min/max of API microversions to version API
    
    As nova-spec api-microversions, versions API needs to expose minimum
    and maximum microversions to version API, because clients need to
    know available microversions through the API. That is very important
    for the interoperability.
    This patch adds these versions as the nova-spec mentioned.
    
    Note:
      As v2(not v2.1) API change manner, we have added new extensions if
      changing API. However, this patch doesn't add a new extension even
      if adding new parameters "version" and "min_version" because version
      API is independent from both v2 and v2.1 APIs.

Release bdm constraint source and dest type
    
    https://bugs.launchpad.net/nova/+bug/1377958 fixed a problem
    that source_type: image, destination_type: local is not
    supported for boot instance, exception should be raised to
    reject the param otherwise it will lead to instance become
    ERROR state.
    
    However the fix introduced a problem on nova client
    https://bugs.launchpad.net/python-novaclient/+bug/1418484
    The fix of the bug leads to following command become invalid
    
    nova boot test-vm --flavor m1.medium --image centos-vm-32
    --nic net-id=c3f40e33-d535-4217-916b-1450b8cd3987 --block-device
    id=26b7b917-2794-452a-95e5-2efb2ca6e32d,bus=sata,source=volume,bootindex=1
    
    So we need to release the original constraint to allow
    the above special case pass the validation check then
    we can revert the nova client exception
    (https://review.openstack.org/#/c/165932/)
    
    This patch checks the boot_index and whether image param is
    given after we found the bdm has source_type: image,
    destination_type: local, if this is the special case, then
    no exception will be raised.

Fix check_can_live_migrate_destination() in ComputeV4Proxy
    
    There was a mismatch in the V4 proxy in the call signatures of this
    function. This was missed because the "destination" parameter is passed
    in the rpcapi as the host to contact, which is consumed by the rpc
    layer and not passed. Since it was not called one of the standard
    names (either host if to be not passed, or host_param if to be passed),
    this was missed.
