Make auth_token return a V2 Catalog

As there is no way to distinguish a v2 or v3 catalog from the headers
provided to an application we will for the meantime always return a v2
catalog. This should not cause any issues as the full token data is not
provided to the service so there is no-one that will get caught out by a
v2/v3 mix, and anyone that is already supporting the v3 catalog format
will have to support the v2 catalog format as well so it will continue
to work.

Move auth_token cache pool tests out of NoMemcache

There were cache pool tests in NoMemcacheAuthToken. Since this class
un-imports memcache, setting the memcached_servers option would just
be ignored anyways.

The tests were moved into a separate class and changed to not set
memcached_servers. The behavior should be the same.

Also, there was a cache pool test in CommonAuthTokenMiddlewareTest
that fit better in this new class.

Cached tokens aren't expired

The auth_token test said that the cached tokens are expired. The
tokens weren't expired, so remove the code.

Move auth_token tests not requiring v2/v3 to new class

The tests in CommonAuthTokenMiddlewareTest run for both v2 and v3
tokens, but contained tests that weren't affected by the token
version.

The tests that aren't affected by the token version are now in
their own class.

Remove importutils from oslo config

The importutils module is only used by other oslo modules, so
remove it from openstack-common.conf. It'll be pulled in
automatically if it's needed.

auth_token hashes PKI token once

auth_token was hashing the PKI token multiple times. With this
change, the token is hashed once.

Auth Plugin invalidation

To allow session to re-fetch a token on an Unauthorized call we add an
invalidate method to auth plugins that is expected to flush all the
current authentication data from the plugin such that it will be
refreshed on next request.

This is then used to reissue requests from session when an Unauthorized
is called.

Add /role_assignments endpoint support

This patch adds role assignments list support
to keystoneclient.

Created RoleAssignment resource and RoleAssignmentManager
classes. RoleAssignmentManager only implements the list()
method, the other inherited methods from base.CrudManager
raises a MethodNotImplemented error with customized messages.

This bp is complimented with the OSC part:
