Clean up warnings about enginefacade

[Jay Pipes]

You see a bunch of the following in Nova's test runs:

Captured stderr:
~~~~~~~~~~~~~~~~
    /home/jaypipes/repos/nova/.tox/py27/local/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:254: OsloDBDeprecationWarning: EngineFacade is deprecated; please use oslo_db.sqlalchemy.enginefacade
      self._legacy_facade = LegacyEngineFacade(None, _factory=self)

We should use oslo_db.sqlalchemy.enginefacade now in all cases.

Changing status back to confirmed. Will see what I can do!

[Sivasathurappan Radhakrishnan (siva-radhakrishnan)]

Jeffrey Augustine Can you please let me know if you are still working in this bug ?

[Jeff Augustine (ja224e)]

Sorry for the delay! Just returning from the summit and should now have time. If no update by the end of week I will release it to you.

[Sivasathurappan Radhakrishnan (siva-radhakrishnan)]

Thanks Jeffrey!

[Sivasathurappan Radhakrishnan (siva-radhakrishnan)]

changing it to confirmed to avoid any confusion on the status of the bug

[Sivasathurappan Radhakrishnan (siva-radhakrishnan)]

Please ignore my previous comment.

I don't see in happening in py27 anymore but I could see single occurrence of it in tox -e py34.

[Danil Akhmetov (dinobot)]

I can't reproduce the problem neither with py27 nor py34: it seems like oslo_db.sqlalchemy.enginefacade is being used everywhere already.

[Markus Zoeller (markus_z) (mzoeller)]

As we use the "direct-release" model in Nova we don't use the
"Fix Comitted" status for merged bug fixes anymore. I'm setting
this manually to "Fix Released" to be consistent.
