Fix bugs for node flush for stop/shutdown/restart

Browse Source 
Previously VMs in stop/shutdown/restart states wouldn't be properly
handled during a node flush. This fixes the bugs and ensures that the
transient VM states (shutdown/restart) are completed before proceeding,
and then avoids setting a stopped/shutdown VM to shutdown/auotstart.
