    Skip middleware request processing for admin token

    In be558717 the request handling was refactored and more of the token
    handling was left to keystonemiddleware. However, when using the
    deprecated admin_token, the token needs to be handled differently.
    Specifically, there may be no 'token' or 'access' key in the body of
    the request, which keystoneauth expects to have keystonemiddleware pass
    to it[1][2]. Luckily the admin_token doesn't need a lot of special
    processing, so we can just skip that step and move on to fill_context.
