Move the logic which volumes are included in the backup job to its own
method and adapt the VZDump code accordingly. This makes it possible to
develop other features around backup jobs.

v5 -> v6: create hash with volume data directly in push call instead of
adding a new variable beforehand
v4->v5:
* use new foreach_volume call
* change $ret_volumes to $return_volumes
* use dedicated variables in PVE::VZDump::QemuServer where hash is used
more than once
* renamed $backup_included and other variables to (IMHO) better names
v3->v4: changed function call for `foreach_drive` to QemuServer::Drive
