[LXD]Lvm thin snapshot shipping support for lvm storagepool move

As i understand with Zfs lxd storagepool move is fast ( as no rsync is involved) as things can be moved from different Zfs Storage pools via snapshot diff.

However no clarity is there for lvm thin snapshot shipping i.e using https://github.com/LINBIT/thin-send-recv OR a slower rsync shall be used(In scenerio where both side pools is lvm thin only)

It uses rsync for filesystem volumes and direct block copy for block volumes.

We have a features matrix which shows which storage drivers support optimized volume transfer:
