For secure guest, FakeReboot kills original QEMU instance and
create new one which is quite different from normal guest.
To reflect this fact, VIR_DOMAIN_EVENT_[STOPPED|STARTED]
are sent to control plane with new introduced reasons
VIR_DOMAIN_EVENT_[STOPPED|STARTED]_RECREATION.
That would let control plane software understand that these
events are from a fake reboot.
