Update VMI pause/unpause (#2596)

removed wait_for_domstate_pause_status from pause/unpause
(when called with wait=True):
  1. check for domstate was an old w/a with is irrelevant now
  2. executing domstate command on virt-launhcer pod can be done
     only with admin client (even though pause/unpause can be
     executed by unpriv client)
