This series brings internal snapshot support at block devices level, now we
have two main methods to do snapshot: 1) backing chain and 2) internal one, and
3) Stefan's unmerged backing up approach. Compared with 1), internal snapshot

Internal snapshot's ID and name concept are both visible in general
