Bug Description

When running just the placement functional tests with `tox -efunctional placement` on a host with sufficient cpus (16 in this case, on a host with only 4 it wasn't happening) some tests can fail because of conf not being properly set with "oslo_config.cfg.NoSuchOptError: no such option oslo_policy in group [DEFAULT]". Example traceback at http://paste.openstack.org/show/728513/

This appears to because in some cases registering the policy opts is happening elsewhere in the processing before running the gabbi tests but only sometimes. This is a symptom of long term global conf leakage that we may wish to consider fixing, but the short term fix is to register the opts in the gabbi fixture. Patch forthcoming.

    Set policy_opt defaults in placement gabbi fixture

    Without this change, tests can intermittently fail with NoSuchOptError
    when a single process does not have other tests running prior to
    gabbi tests. This change ensure the opts are registered and defaulted.
