      Using Trident CSI driver and a VolumeSnapshotClass with "Delete" deletionPolicy.

      As per upstream documentation https://velero.io/docs/v1.12/csi/

      VolumeSnapshots created by the Velero CSI plugins are retained only for the lifetime of the backup even if the DeletionPolicy on the VolumeSnapshotClass is set to Retain. To accomplish this, during deletion of the backup the prior to deleting the VolumeSnapshot, VolumeSnapshotContent object is patched to set its DeletionPolicy to Delete. Deleting the VolumeSnapshot object will result in cascade delete of the VolumeSnapshotContent and the snapshot in the storage provider.

      Was observed that several snapshots are still retained on the storage backend after the backup expires.
      VSC and VS objects on the API are deleted correctly, so this might indicate that this patch might not be working as expected.
