    Test the correct placement endpoint with multiple regions

    In a multi-region setup (not yet supported but there are plans to
    support it) the nova_wait_for_placement_service.py script might check
    the wrong placement endpoint.

    This change makes the script explicitly look for the endpoint in the
    correct region.
