Gracefully shutdown vSphere VMs

[mansam]

Fixes the VMWare client's StopVM to use ShutdownGuest instead of PowerOff. This will require the VMWare Tools to be installed on the guest.

This uses the same polling mechanism as the oVirt provider to wait for the shutdown to complete, which can block for up to 5 minutes. I assume that since that's what the oVirt provider is doing that it's acceptable, but if not I have also worked on an alternative approach which involves setting a new condition and re-queuing the reconcile until the source VM powers off or times out.
