Describe the solution you'd like
Currently when trident creates GCNV volume for every PVC, We need to go to each GCNV volume and attache the volume to backup policy or create snapshot policies in all GCNV vaolume manually.

Since PVs are dynamic in Kubernetes with trident, Its administrative overhead to attach backup policies and snapshot policies in each PVs/GCNV volume.

If there is a away to add backup policy in trident backend itself or may be storage class parameters, which will automatically add backup policy to all the GCNV volume created dynamically by trident, That will be very helpful.
