Issue

Management of CSI Snapshots, specifically the deletion doesn't work after renaming the SVM in ONTAP.
 
This means that Astra Control Center's Snapshot/Backup retention stops working.
 
Showing information about the Snapshot shows that the CRD information is still present:
# kubectl describe volumesnapshots pvc-<PVC_UID>-snap-<SNASHOT_UID> -n <NAMESPACE>
Name:         pvc-<PVC_UID>-snap-<SNASHOT_UID>
Namespace:    <NAMESPACE>
Labels:       app.netapp.io/managed-by=astra.netapp.io
Annotations:  <none>
API Version:  snapshot.storage.k8s.io/v1
Kind:         VolumeSnapshot
...
 
However, manual deletion appears to work:
mebis-vp:~/acc-test> kubectl delete volumesnapshots pvc-<PVC_UID>-snap-<SNASHOT_UID> -n <NAMESPACE>
volumesnapshot.snapshot.storage.k8s.io "pvc-<PVC_UID>-snap-<SNASHOT_UID>" deleted
