Yes, since PVE 4.0 watchdog fencing is the norm.
There is a patch set of mine which implements the use of external fence device,
but it has seen no review. I should probably dust it up, look over it and re send

No, at the moment external fence devices are not integrated.
You can expect an faster recovery with external fence devices, at least in
simple setups (i.e., not multiple fence device hierachy)
