    [qos] cleanup _find_object from neutron.db.api
    
    Instead of having a separate function for id-based search, make
    get_object accept any kwargs, including id=, and reuse it everywhere
    where we used _find_object before.

    Revert "Mute neutron.callbacks notification logs."
    
    This reverts commit e19eb49c1c066c8fa4a3c19183bca1daef553a5c.
    
    We don't use callbacks to extend resources, so no need to mute the logs.

    Base infrastructure for QoS API tests
    
    This introduces the basic methods in the tempest client, that allow the
    testing of the QoS plugin. This also contains 2 (very) simple tests
    which test creation and deletion of both policies and bandwidth rules,
    as well as list/show for both resources. While creation is done
    explicitly, deletion is done implicitly (all resources are deleted after
    the test, during tearDown)
    
    Minor fixes to the QoS plugin are included as well.

    Handle qos_policy on network/port create/update
    
    Added handling for qos_policy_id field in the network and port
    entities via ML2 extension driver.
    The QoS profile will be associated to the network/port when requested as
    part of the entity creation or update.
    
    Allow ML2 extension manager to not register for any api extension
    (new use case).
    
    ===
    
    Extend the resources using the QoS extension class
    
    Since the QoS extension for plugins is handles by this class, it makes
    sense for it to handle also property extension of resources.
    
    For ML2 this means that that extend_{network,port}_dict functions will
    handle the extension of resources by calling QosExtensionHandler.
    This logic can easily be reused by other plugins.
    
    Note: we should make sure that resource extension does not require db
    access, otherwise we see DBDeadLock errors and random tempest failures.
    To achieve this, we define a new SQLAlchemy joined relationship on
    policy bindings to make networks and ports receive those bindings on
    their fetch from database. After that, the only work to do left for
    resource extension handler is to copy the fetched policy into resource
    dictionary.
    
    ===
    
    Also enable new qos ml2 extension until we configure it in gate via
    project-config and devstack-gate to make sure it's enabled and tested.

    objects.qos.policy: support per type rule lists as synthetic fields
    
    This is a significant piece of work.
    
    It enables neutron objects to define fields that are lazily loaded on
    field access. To achieve that,
    
    - field should be mentioned in cls.synthetic_fields
    - obj_load_attr should be extended to lazily fetch and cache the field
    
    Based on this work, we define per type rule fields that are lists of
    appropriate neutron objects. (At the moment, we have only single type
    supported, but I tried hard to make it easily extendable, with little or
    no coding needed when a new rule type object definition is added to
    rule.py: for example, we inspect object definitions based on
    VALID_RULE_TYPES, and define appropriate fields for the policy object).
    
    To implement lazy loading for those fields, I redefined get_by_id for
    rules that now meld fields from both base and subtype db models into the
    corresponding neutron object.
    
    Added a simple test that checks bandwidth_rules attribute behaves for
    policies.
    
    Some objects unit test framework rework was needed to accomodate
    synthetic fields that are not propagated to db layer.

    Initial implementation of the QoS service plugin that just implements
    CRUD for policy and rule.
    
    There are no tests yet.
    
    path_prefix is now provided as an attribute to the plugin base, since
    that's required by the COMMON_PREFIXES removal from master branch.

    Add oslo db retry decorator to non-CRUD actions
    
    The previously added decorators to the create and update handlers
    in the API layer only applied to actions that followed the standard
    create/update path. However, for API operations like add_router_interface,
    a different path is followed that wasn't covered by a retry decorator.
    
    This patch adds the decorator to handle deadlocks in those operations as
    well.

    objects.base: fixed object.delete()
    
    It was using wrong call to delete an object from a session.
    
    Also, expanded test_create() test to check all basic operations:
    get_by_id, create, update, and delete.
    
    To facilitate update() check, introduced a new field for objects called
    fields_to_update that stores names of fields that are not expected to be
    updated in an object. This allows us to keep the above mentioned test
    untangled from specific object type.
    
    Also made get_by_id() behave correctly (returning None) if the object
    does not exist.

    objects.base: reset changes after getting objects from database
    
    Now all objects are comparable.
    
    We need to reset changes, otherwise an object that is constructed and
    .create()d is different from the one that is .get_by_id()d from database
    (for primitive serialization contains list of changed fields for
    versioned objects).
    
    Added initial sql test case for objects (just create-fetch for policy
    for now, but can be easily extended to other types).

    AgentExtensionsManager and AgentCoreResourceExtension
    
    This patch introduces the following classes:
    L2Agent - abstract class for common L2Agent implementions.
    AgentExtensionsManager - to load AgentCoreResourceExtension.

    This allows better segregation between L2 Agent Core
    and L2 Agent Extensions.
    
    The patch is missing unit test but it was tested manually.
    I added a unit tests @TODO comments to come back
    to them later.

    Generic rpc callback mechanism which could be reused
    
    This is a publisher/subscriber messaging mechanism optimized
    for agent consumption and server production without the need
    of creating new rpc messages when new resources are introduced.
    
    Oslo versionedobjects are the perfect match to ensure
    cross version compatibility even if the published/subscribed
    resources format change over time.
    
    This is still a basic stub allowing get_info of the resources,
    and the next change will introduce the RPC methods to call
    get_info: I0ac8a009e781b6edb283d8634b1a2f047db092dc
    
    The plugin is returning stub objects to be consumed from the
    agent to test the basic behaviour until we have DB.
    
    TODO: Update documentation, according to code changes,
          enforce versioned objects only doing deserial/serialization.

    Add extension callbacks support for networks
    
    Add callbacks for extention to the network resource so that interested
    extensions can do custom logic when a network is created or updated.
    
    Currently it will be done the same way port notifications are done -
    i.e. only in ML2 plugin. We can revisit this in a floow up patch if the
    whole notification logic should be moved somewhere else as this merits

    First QoS versioned objects, ever
    
    Well, first versioned objects in the tree.
    
    Binding to networks and ports is not implemented.
    
    No tests. Checked manually.

    QoS: db models and migration rules
    
    This patch includes db models and migration rules for initial QoS objects.
    
    Comparing to the spec, it adds two more service tables to maintain links
    between networks and ports and their respective policies. We maintain
    uniqueness as a unique constraint.
    
    In some parallel world, we could have an additional field for networks
    and ports that could be nullable to point to a policy. That said, it
    breaks qos isolation a bit, and will also be a bit more painful if and
    when we decide to spin out qos service pieces outside the tree.

    docs: link quality of service doc stub to devref index
    
    Since I433126a8247e7e1c316f2c96bb21e15582b247ce, doc warnings are
    considered as failures in gate.
    
    Unlinked .rst file generates one, making docs job broken for
    feature/qos. Same for an empty file with no title.

    QoS service plugin stub
    
    This patch introduces the QoS service plugin which implements
    a stub of the API extension.
    
    This is patch is a basic step to be able to create an experimental
    job enabling this service so we can do api tests.

    Create the QoS API extension stub
    
    This patch introduces the QoS API extension, in a basic
    form where we could, in combination with the service plugin
    stub, start creating some experimental test jobs that install
    the service plugin.
    
    Please not that URL mapping is not fully according to spec,
    neither it does include any testing. We need to work that out.
