Summary: Before this, we directly mounted the the rawfile on the mountpoint. In this revision the `STAGE_UNSTAGE_VOLUME` capability is implemented, meaning that the volume is first mounted to a staging path, and then `bind`-mounted to the actual path. This way we can free up loopback devices when they are not needed. Test Plan: - Create a pvc, and use it inside a pod - Run `losetup -l` on the node running the pod, and assert the creation of a loop device - Delete the pod, but not the pvc - Run `losetup -l` on the same node, and assert the removal of the loop device Reviewers: h.marvi, bghadiri Differential Revision: https://phab.hamravesh.ir/D806
