In some situations, users might need to shutdown / scale down the operator to perform some manual maintenance. If they do this while using StrimziPodSets, it would mean that all their Pods will be left without the controller and will not be restarted in case of disruptions. To help avoid this, the Cluster Operator will have a switch which would allow it to be configured to do only StrimziPodSet reconciliation. When the switch is enabled, it will do only reconciliations of StrimziPodSets but it will not reconcile any other resources. This will be also useful in the future with stretch clusters, where it would allow to deploy local copy of the Cluster Operator on each cluster to handle only the StrimziPodSets while the management of the other resources will be done remotely.
