Barbican plugin needs config it could get from catalog

[Duncan Thomas]

The cinder barbican plugin requires both the barbican and the keystone endpoints to be hard coded in cinder.conf, when both are usually present in the service catalog

[Jeremy Liu (liujiong)]

This should be fix released for now!

Change abandoned by Nate Potter (<email address hidden>) on branch: master
Review: https://review.openstack.org/346981
Reason: These files were removed from cinder and moved to castellan - these fixes will need to be made there.

The barbican endpoint is found from the service catalog if there is no value in the config file:

[Kaitlin Farr (kaitlin-farr)]

Ok, but I can see how it would be useful to reuse the auth_url from the [keystone_authtoken] section since it's already there.

    Fix retrieving barbican endpoint from service catalog

    The context wrapper classes under castellan.common.credentials were
    missing an auth_url property resulting in calls to get_endpoint()
    failing with 'Could not determine a suitable URL for the plugin' unless
    users set barbican/auth_endpoint.
