Backport to include HA Cluster PMDA in PCP as the sub-package pcp-pmda-hacluster.
I'm creating this bz for 8.4 and marking it CLOSED -> CURRENTRELEASE as this functionality is in 8.4 and then we can get it cloned for 8.2 & 8.1.
Closing this 8.5 variant of this BZ once more - the requested zstream clone work has been completed now, and the original fix was included via rebase.
