Subject: [PATCH 2/5] Fix: pacemaker-attrd: sync utilization attributes to
peers correctly
Include the set type with attribute syncs.
Previously, utilization attributes would have the correct set_type on the node
where they were set, but peers would store it as a regular node attribute. If
one of those peers became writer, the attribute would get written to the wrong
set.
