Annotations for master/t-server PVCs

[hau21um]

We us https://github.com/topolvm/pvc-autoresizer to autoresize volumes in our projects.
To make this working also for yugabyte PVCs, we would need to set annotations also on persistence volume claim level.
Wold be nice to have this option through ie. "Values.storage.[tserver|master].annotations". We usually generate 2-3 annotations, but can be event more.
