Bug description and how to reproduce:
For shared ebs volume, it would be very useful if we could tag it from the cluster configuration.
For example, it would work well for us if we could create a volume with a cluster and set the DeletionPolicy to Delete, but we would want to tag this volume for backup service backup.
