    retry on authentication failure in api_client

    Due to eventlet threading weirdness, it appears that sometimes a request
    that is destined for the compute api fixture ends up on the placement
    api fixture. The latter uses a no auth middleware that 401s when it does
    not get a token.

    The change retries the auth request a few times before failing.

    If this has no effect, doing an eventlet.sleep() before the retry might
    be something worth trying.
