Convert auth to flask native dispatching

Convert the /auth paths to flask native dispatching.

A minor change to additional_urls was implemented to ensure all
urls are added at once instead of individually (causing an over-
write issue within flask as a single resource may only have a
single set of URL mappings).

Alternate URLs now support adding alternate JSON Home rel links.
This is to support the case of OS-FEDERATION auth routes moving
to /auth. The old JSON Home entries must exist but reference
the new paths.

This port includes the following test changes (needed due to the
way flask handles requests and the way requests are passed through
the auth system):

* Implemented keystone.common.render_token (module)
  containing render_token_response_from_model and use it instead
  of keystone.common.controller.render_token_response_from_model.

  Minor differences occur in render_token_response_from_model in
  the keystone.common.render_token module, this is simply
  for referencing data from flask instead of the request object.

* Test cases have been modified to no longer rely on the auth
  controller(s) directly

* Test cases now use "make_request" as a context manager
  since authenticate/authenticate_for_token directly
  reference the flask contexts and must have an explicit
  context pushed.

* Test cases no longer pass request objects into methods
  such as authenticate/authenticate_for_token or similar
  methods on the auth plugins

* Test cases for federation reference the token model now
  where possible instead of the rendered token response.
  Rendered token responses are generated where needed.

* Auth Plugin Configuration is done in test core as well.
  This is because Auth controller does not exist.

NOTE: This is a massive change, but must of these changes
were now easily uncoupled because of how far reaching auth
is.
