Fix django.contrib.auth.middleware monkey patching
The "request" attribute is not available in
openstack_auth.backend.KeystoneBackend.get_user when session data is restored
and it's the first request to happen after a server restart.
As stated by the function document, the "request" attribute needs to be
monkey-patched by openstack_auth.utils.patch_middleware_get_user
for this function to work properly.
This should happen in openstack_auth.urls at import time. But there is nowhere
in Horizon where this module is imported at startup. It's only introspected
by openstack_dashboard.urls due to AUTHENTICATION_URLS setting.
Without this monkey-patching, the whole authentication mechanism falls back
to "AnonymousUser" and you will get redirected to the login page due
to horizon.exceptions.NotAuthenticated being raised by
horizon.decorators.require_auth as request.user.is_authenticated will be False.
But if a user requests a page under auth/, it will have the side-effect of
monkey-patching django.contrib.auth.middleware as expected. This means that
once this request is completed, all following requests to pages other than
the ones under auth/ will have there sessions properly restored and
you will be properly authenticated.
Therefore this change introduces a dummy middleware which sole purpose is
to perform this monkey-patching as early as possible.
There is also some cleanup to get rid of the previous attempts at
monkeypatching.
