By the way, am I missing something when I think that this extension is
already covered if you're:
1. Looking to get the node out of the scheduling loop, you can just
disable it with os-services/disable?
2. Looking to evacuate instances off a failed host (or one that's in
"maintenance mode"), just use the evacuate server action.
