Currently a user is allowed to specify either a resource ID or name
when running openstack identity comands. In some cases, when a name
is specified instead of an ID, the command will return as not able
to find the resource when it in fact does exist.
The changes here are to check the client against the token on such
requests and to extract the ID of the resource specified if enough
information exists between the two. We then use the ID associated
with the resource to complete the user requests.
