Description

Kudu clusters need full-duplex connectivity inside of Raft configurations (masters or tservers), as well as between masters and tservers themselves. No doubt users will run into all sorts of issues with only partially configured firewalls.

Let's do what we can to surface connectivity failures, be they inside of a Raft configuration or between a particular master and tserver. Metrics, log output, and web UI dashboards are all good places to surface these failures.
