- Give terminal phase correctly to all pods that will not be restarted. 

  In particular, assign Failed phase to pods which are deleted while pending. Also, assign a terminal 
  phase (Succeeded or Failed, depending on the exit statuses of the pod containers) to pods which
  are deleted while running.
  
  This fixes the issue for jobs using pod failure policy (with JobPodFailurePolicy and PodDisruptionConditions
