vm: add the transient disk support

A transient disk is a temporary qcow layer based on a (usually
internal) volume that is attached to a VM in read-write mode.
All changes stored in the transient disk will be lost as soon
as the disk is hot-unplugged or when the VM exits.
Its primary use is to access in read-write mode a snapshot
(read-only volume).
Libvirt doesn't support transient disks yet, hence this patch
includes also all the required parts to fill that gap.
