title: OpenStack Grizzly keystoe remove_user command removing ALL users
body: <p>I have the following code that works great in Folsom:</p>
  
  <pre><code>#remove the user for each role associated with the user
      user_roles = kc.users.list_roles(obj_id, currtenant)
      for role in user_roles:
          if obj_id == user.id:
              kc.tenants.remove_user(currtenant, obj_id, role.id)
  </code></pre>
  
  <p>That same code will remove ALL users rather than just the user with the id, obj_id from the tenant specified.  anyone else have this issue in Grizzly?</p>
