LVM snapshot lab

The setup script will setup everything LVM related.

You can then run various scripts generated in /root/ to do various things:

/root/mount-snapshot.sh will mount the snapshot as readwrite

/root/restore-snapshot.sh will restore the snapshot

/root/merge-snapshot-into-main.sh will merge the contents of the snapshot. This merge is actually a replace.

`/root/remove-snapshot.sh will remove the snapshot
