wspoon: Create fan rotors group with hard poweroff

In migrating to support better fan failure/missing shutdown scenarios,
currently defined shutdown scenarios should monitor the functional
states of the fan enclosures and do a soft poweroff.

A system hard poweroff will occur for the following condition:
 - More than two fan rotors are nonfunctional
