common-ha: add cluster HA status to --status output for gdeploy
gdeploy desires a one-liner "health" assessment. If all the VIP and port block/unblock RAs are located on their prefered nodes and 'Started', then the cluster is deemed to be good (healthy). N.B. status originally only checked the "online" nodes obtained from `pcs status` but we really want to consider all the configured nodes, whether they are online or not. Also one `pcs status` is enough. Change-Id: Id0e0380b6982e23763edeb0488843b5363e370b8 BUG: 1395648 Signed-off-by: Kaleb S.
