Problem Statement

I've been hitting cases where kubernetes cluster actions are blocked due to priorityClass being absent after a helm install --upgrade.

For example:

  Type     Reason        Age                  From                    Message
  ----     ------        ----                 ----                    -------
  Warning  FailedCreate  3m (x1405 over 11h)  statefulset-controller  create Pod elasticsearch-data-2 in StatefulSet elasticsearch-data failed error: pods "elasticsearch-data-2" is forbidden: no PriorityClass with name elasticsearch-data was found```
