Title: Report membership change results to singleton ResultCollector

Measure the time it takes to join until the node notice itself as Up and until all nodes have confirmed the new node as Up. Report this and other membership/reachability observations to one central node.

Changed acceptable-heartbeat-pause to 0s to see reachability instability early.
I have tried this on a small EC2 cluster over night and no unreachable reported.
