Preserve the pvcs when deleting a K8ssandraCluster

If there is an accidental deletion . The data will be lost forever .But if this feature exists. we can toggle whether to keep data or destroy altogether.

Environment

Anything else we need to know?:

The data is preserved in PVs, not PVCs. k8ssandra-operator does not delete the PVs, that's controlled by your StorageClass.

[berginv]

Yes, you are correct . Please assume this scenario where I delete my k8ssandra cluster and recreate with no change. The operator will delete the PVCs and then recreate it, which will create a new PV (provisioned by storage class). In this scenario I can't use my existing PV. It would be good if there is a toggle as in this Reference
