+features:
+ - With the composable HA work landed it is now possible
+ to split pacemaker-managed services like galera, rabbit,
+ redis, haproxy and any A/P resource, off to dedicated
+ nodes. These services can be split off to separate nodes
+ either via the normal Pacemaker service (which has a limit
+ of 16 maximum number of nodes) or via the newer PacemakerRemote
+ service (but not both on the same node). Note that until
+ https://bugzilla.redhat.com/show_bug.cgi?id=1417936 is fixed,
+ PacemakerRemote should only be used for Cinder A/P resources
+ and Manila A/P resources.
