Subject: [PATCH] user status method.   Now the sub_role shall be sat with it's
 status in order to record sub_role status into user object. Sub_role can be
 removed normally and the method check_status_record  will make sure data is
 being saved as it should be. Also unnecessary role will be removed if no sub
 role exists.
