1. All vzdump changes are in ~80 lines, but it greatly increases usability
of vzdump. In most cases there's no reason to use custom / external backup
system, because vzdump is enough and is nicely integrated in Proxmox's UI.

2. The only external dependency is xdelta3. You can use stock if you want,
but there's missing lzop support.

3. Using differential backup is less efficient than incremental, but the
easiest to implement.

4. There are cases where you can't use lessfs. We have NAS service where
only nfs is available.

We want to keep vzdump a simple tool.
