Subject: [PATCH] Add the noop management interface to the redfish hardware
type
Apparently, we're hitting similar problems on some hardware that caused
us to add noop to ipmi. Maybe we should make it supported on all
hardware types, but right now it would break iLO. To reduce the scope
of this (hopefully backportable) patch, I'm limiting it to Redfish.
