Subject: Cleanup merge of user/group helpers into Identity interface.  Reduce
 redundant code in the user module and remove references to the Identity
 helper from the user module as the user module should be able to access
 things directly. Simplify the get_user_list api method to just accept an
 array of ids to return user objects for.
