Monitoring Kubed

Kubed has native support for monitoring via Prometheus. Kubed operator exposes Prometheus native monitoring data via /metrics endpoint on :56790 port. You can setup a CoreOS Prometheus ServiceMonitor using kubed-operator service. To change the port, use --web.address flag on Kubed operator.
