Fix token issue after auth changeup

IssueToken.take_action() was missed in updating the structure of
the ClientManager.

Also, TOKEN_WITH_TENANT_ID in v3 is just wrong...

Closes-Bug: #1383396

Change-Id: If2dd82a26af1d743ee9df73e0c1aebce497bf22e
Merge "Fix token issue after auth changeup"
Clean up shell authentication

* Remove the auth option checks as the auth plugins will validate
  their own options
* Move the initialization of client_manager to the end of
  initialize_app() so it is always called.  Note that no attempts
  to actually authenticate occur until the first use of one of the
  client attributes in client_manager.  This leaves
  initialize_clientmanager() (formerly uathenticate_user()) empty
  so remove it.
* Remove interact() as the client_manager has already been created
  And there is nothing left.
* prepare_to_run_command() is reduced to trigger an authentication
  attempt for the best_effort auth commands, currently the only
  one is 'complete'.
* Add prompt_for_password() to ask the user to enter a password
  when necessary.  Passed to ClientManager in a new kward pw_func.

Merge "Clean up shell authentication"
Change --os-auth-plugin to --os-auth-type

User's don't know what a plugin is.

* Internally, os_auth_type and/or auth_type represents what the
  user supplied.
* auth_plugin_name is the name of the selected plugin
* auth_plugin is the actual plugin object

Plugin selection process:
* if --os-auth-type is supplied:
  * if it matches against an available plugin, done
  * (if it can map to an availble plugin type, done; TODO in a followup)
* if --os-auth-type is not supplied:
  * if --os-url and --os-token are supplied, select 'token_endpoint'
  * if --os-username supplied, select identity_api_version + 'password'
  * if --os-token supplied, select identity_api_version + 'token'
