* move auth option checking back to OpenStackShell() to keep the shell-level
interaction at that level; add checking for token flow options
* make identity.client.make_client() configure keystoneclient.v2_0.Client()
properly for both password flow and token flow auth
* eliminated ClientManager.init_token(), set _service_catalog in __init__()
* compute client handles token flow

* Make the Identity client in identity.client.make_client()
* Auth via ClientManager.identity
* Skip extra auth roundtrip in compute client

bug 992841
Move the authentication logic into a new ClientManager class so that only commands that need to authenticate will trigger that code.
Implement "list server" and "show server" commands as examples of using the ClientManager, Lister, and ShowOne classes.
