UnsupportedServiceVersion: Service placement has no discoverable version. The resulting Proxy object will only have direct passthrough REST capabilities.

[Matt Riedemann]

I'm seeing this all over the nova tox functional job console logs since the placement client code in nova was changed to use the openstacksdk:

https://logs.opendev.org/61/673961/1/gate/nova-tox-functional-py36/a4cb2af/job-output.txt.gz#_2019-08-01_17_51_24_070487

2019-08-01 17:51:24.070487 | ubuntu-bionic | b'/home/zuul/src/opendev.org/openstack/nova/.tox/functional-py36/lib/python3.6/site-packages/openstack/service_description.py:224: UnsupportedServiceVersion: Service placement has no discoverable version. The resulting Proxy object will only have direct passthrough REST capabilities.'

I don't know if this is a nova problem, or an sdk problem, or a placement problem, but it's chewing up the functional job logs so if it's external to nova we should add a warnings filter in our tests to only log this once.

It's a combination of the switch to use the sdk and Placement being not quite flexible enough.

    Filter UnsupportedServiceVersion warning

    Add the following warning emitted in functional tests
    to the filterwarnings.

      UnsupportedServiceVersion: Service placement has no discoverable
      version. The resulting Proxy object will only have direct passthrough
      REST capabilities.

    The warning is emitted because there is not a service description
    (pairs of a suppoerted version and a proxy class) for placement service
    in openstacksdk.
    So set the filter until the service description for placement service
    is added in openstacksdk.
