    Use a placement conf when testing report client

    It turns out that the independent wsgi interceptors in
    test_report_client were using nova's global configuration
    when creating the intercepts using code from placement.
    This was working because until [1] placement's set of conf
    options had not diverged from nova's and nova still has
    placement_database config settings.

    This change takes advantage of new functionality in the
    PlacementFixture to allow the fixtur to manage config and
    database, but _not_ run the interceptor. This means it
    can set up a config that is later used by the independent
    interceptors that are used in the report client tests.
