[Improvement] Restore API should transfer ownership explicitly

[shanshanying]

Restored PVC has no owner reference and it is not safe for InstanceSet to adopt arbitary PVCs created by others (the pvc could be provided by external systems, or created by users, etc)

Intead, Rrestore API should set explicitly whom to transfer the ownership to. Using internal labels or annotations are too obscure.
