Incorrect arrow source for Auth in Glance architecture image

[Olena Logvinova]

The image at http://docs.openstack.org/developer/glance/architecture.html needs to be updated:

1. glance_store doesn't have authorization, but the authentication only.
2. AuthZ -> AuthZ Middleware for clarity
3. Added an arrow to reflect an optional call from REST API to AuthZ Middleware
