feat: speed-up volume migration procedure
Modified the volume migration procedure - add option to skip the deep-copy step, in order to speed up the procedure:
- old steps:
- create src snapshot
- delete dst volume
- clone snapshot
- flatten clone
- deep-copy clone to dst volume
- delete clone
- delete snapshot
- new steps:
- create src snapshot
- delete dst volume
- clone snapshot to dst volume
- flatten clone
- delete snapshot
