Filer, S3 and broker report it on the KeepConnected registration, volume servers in their heartbeat, and masters return their own in GetMasterConfiguration. MasterClient gains SetMetricsPort so the eight callers that have no metrics listener are untouched, and the volume server takes it as a constructor argument because its heartbeat goroutine starts there. In combined "weed server" one metrics listener serves the whole shared registry, so every component advertises the same port.
