* Domains now have a list of owners, which are ``IUser`` objects, instead of

   the single ``contact_address`` they used to have.  ``IUser`` objects now
   also have a ``is_server_owner`` flag (defaulting to False) to indicate
   whether they have superuser privileges.  Give by Abhliash Raj, with fixes
   and refinements by Barry Warsaw.  (LP: #1423756)

 * Domains can now optionally be created with owners; domain owners can be
   added after the fact; domain owners can be deleted.  Also, users now have
   an ``is_server_owner`` flag as part of their representation, which defaults
   to False, and can be PUT and PATCH'd.  Given by Abhilash Raj, with fixes
   and refinements by Barry Warsaw.  (LP: #1423756)
