To implement <transient/> disks we'll need to install an overlay on top of the original disk image which will be discarded after the VM is turned off. This was initially implemented by qemu but libvirt never picked up this option as the overlays were created by qemu without libvirt involvment which didn't work with SELinux. With blockdev the qemu feature became unsupported so we need to do this via the snapshot code anyways. The helpers introduced in this patch prepare a fake snapshot disk definition for a disk which is configured as <transient/> and use it to create a snapshot (without actually modifying metadata or persistent def).
