[feature] Add option to allow VolumeOp to re-use PVC

[midhun1998]

Feature Area

/area sdk

What feature would you like to see?

VolumeOp should allow re-using of existing PVC.

What is the use case or pain point?

When we have a VolumeOp component in a recurring-run pipeline the component creates new PVC every time a recurring run happens. However, In a use case where the subsequent runs should use the same PVC as the first run, the VolumeOp fails to handle this case.

Is there a workaround currently?

I understand we can create spec using V1PersistentVolumeClaim and pass it as k8s_resource argument but this seems to defeat the purpose of VolumeOp in the first place.

If this seems to be a useful feature I would be happy to create a PR.
