Automatic cleanup and replacement in case when k8s node is lost

In case when your k8s cluster loses one of the nodes due to incident or explicit removal, Scylla Pods may become unschedulable due to PVC node affinity.

When automaticOrphanedNodeCleanup flag is enabled in your ScyllaCluster, Scylla Operator will perform automatic node replacement of a Pod which lost his bound resources.
