Provide support to add/remove mdev in a guest domain, which is in
shut-off or running state (hotplug/unplug). Also support update of
already existing mdev device, when the guest domain is in shut-off
state. Please note that libvirt does not support update of mdev
device, when the guest domain is in running state.
