[Feature Request]: Snapshot clone usability 4. Put all snapshots related command together

### Is there an existing issue for the same feature request?

- [x] I have checked the existing issues.

### Is your feature request related to a problem?

```Markdown
Add a new command, snapshot. So that all snapshot related commands are grouped together.

Snapshot restore
Snapshot diff
Snapshot merge
Etc.

I do understand sql flavor is,
Create snapshot
Drop snapshot
Show snapshot

So I will accept …
Restore snapshot
Diff snapshot
Merge snapshot

But I think putting snapshot first is easier to parse. Either way.
```
