Fix "help" command and implement "list server" and "show server"

blueprint client-manager
blueprint nova-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.
