Cleanup and add clarification to the documentation
for using Keystone auth.
Update to refer to auth_token middleware being
distributed as part of the keystomemiddelware project
rather than keystone.
Include capabilities (/info) in the list of reasons
why delay_auth_decision might need to be set in
auth_token middleware config.
Add description of the project_id:user_id format
for container ACLs and emphasize that ids rather than
names should be used since this patch has now merged:
