    Identify the keystone service when raising 503

    When the keystonemiddleware is used directly in the WSGI stack of an
    application, the 503 that is raised when the keystone service errors
    or cannot be reached needs to identify that keystone is the service
    that has failed, otherwise it appears to the client that it is the
    service they are trying to access is down, which is misleading.

    This addresses the problem in the most straightforward way possible:
    the exception that causes the 503 is given a message including the
    word "Keystone".

    The call method in BaseAuthTokenTestCase gains an
    expected_body_string kwarg. If not None, the response body (as
    a six.text_type) is compared with the value.
