VMWare: should use ShutDownGuest to do grace OS shutdown and then
force power off if timeout passed
Status in OpenStack Compute (nova):
With currently vmware driver. the power_off will explicitly calls
In this case, If a virtual machine is writing to disk when it receives
a Power Off command, data corruption may occur.
Actually in SDK, there is another method
ShutdownGuest which will issues a command to the guest operating system
asking it to perform a clean shutdown of all services.
So it is suggest to use ShutdownGuest first and wait for some
interval, if the power state is still up, make a force shutdown.
