f4c229a41d etcdserver: add livez and ready http endpoints for etcd. 
Add two separate probes, one for liveness and one for readiness. The liveness probe would check that the local individual node is up and running, or else restart the node, while the readiness probe would check that the cluster is ready to serve traffic. This would make etcd health-check fully Kubernetes API complient.

9915d02022 *: Change gRPC proxy to expose etcd server endpoint /metrics 
This PR resolves an issue where the `/metrics` endpoints exposed by the proxy were not returning metrics of the etcd members servers but of the proxy itself.
