    [placement] re-use existing conf with auth token middleware

    If 'oslo_config_project' is passed to the auth_token filter
    factory, the mechanism in nova.api.openstack.placement.wsgi for
    overriding the location of the configuration file is ignored
    meaning that expected custom configuration is also ignored.

    Instead pass the already existing conf with 'olso_config_config'
    parameter.

    The unit test in test_deploy.py shows that the configuration
    settings get passed to the middleware and used by testing the
    value of the 'WWW-Authenticate' header (which comes from a few
    different configuration settings, of which is 'auth_uri') in
    a response generated by the placement WSGI application.
    The same test against the previous deploy.py code fails.
