Why are these changes needed?
Currently, operator doesn't handle the failed pods. When pod is evicted, it just raise error and operator keeps requeue the item. From user journey side, we actually like to replace the head pod with a healthy one. This change catch the evict pod and delete it in the current loop, the next reconcile loop triggered by pod deletion will find the head missing and create a new pod instead.
