[Users] Issues starting hosted engine VM

It was paused due to the connection loss to the NFS server, I would assume
once the connection is restored it could attempt to restore it? But I can
try dig up the vdsm logs if you want, they would only be a few hours old

I think having an option like --vm-resume would at least hide the reason of
having to dig into virsh and messing with authentication at the very least.
