    work fine when the nodes are behaving themselves.
    
    1) geni_update_users: Takes a slice credential and a keys argument. Can
      only be invoked when the sliver is in the started/geni_ready state.
      Moves the slice to the geni_updating_users state until all of the
      nodes have completed the update, at which time the sliver moves back
      to started/geni_ready.
    
    2) geni_updating_users_cancel: We can assume that some nodes will be whacky
      and will not perform the update when told to. This cancels the
      update and moves the sliver back to started/geni_ready.
    
    A couple of notes:
    
    * The current emulab node update time is about three minutes; the
      sliver is in this new state for that time and cannot be restarted or
      stopped. It can of course be deleted.
    
    * Should we allow restart while in the updating phase? We could, but
      then I need more bookkeeping.
    
    * Some nodes might not be running the watch dog, or might not even be
      an emulab image, so the operation will never end, not until
      canceled. I could add a timeout, but that will require a monitor or
      adding DB state to store the start time.
