Round 1 of changes for keystone integration.

 * Modified request context to allow it to hold all of the relevant data from the auth component.
 * Pulled out access to AuthManager from as many places as possible
 * Massive cleanup of unit tests
 * Made the openstack api fakes use fake Authentication by default

There are now only a few places that are using auth manager:
 * Authentication middleware for ec2 api (will move to stand-alone middleware)
 * Authentication middleware for os api (will be deprecated in favor of keystone)
 * Accounts and Users apis for os (will be switched to keystone or deprecated)
 * Ec2 admin api for users and projects (will be removed)
 * Nova-manage user and project commands (will be deprecated and removed with AuthManager)
 * Tests that test the above sections (will be converted or removed with their relevant section)
 * Tests for auth manager
 * Pipelib (authman can be removed once ec2 stand-alone middleware is in place)
 * xen_api (for getting images from old objectstore. I think this can be removed)
