Node health attributes are not being reported

[rpallai]

The ha_cluster_pacemaker_node_attributes metric does not expose node health attributes, even though these are important to monitor on clusters where Node Health Tracking is in use.

The attributes are present in Pacemaker, but they do not appear in the exported metrics:

scf9a# attrd_updater -n '#health-iowait' -U yellow

scf9a# attrd_updater -n '#health-iowait'
name="#health-iowait" host="scf9a" value="yellow"
