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.

etcdserver: remove redundant len check in health check
...
From the Go specification [1]:
"1. For a nil slice, the number of iterations is 0."
`len` returns 0 if the slice or map is nil [2]. Therefore, checking
`len(v) > 0` around a loop is unnecessary.

etcdserver/api/etcdhttp: log successful etcd server side health check in debug level
...
When we have an external component that checks /health periodically, the
etcd server logs can be quite verbose (e.g., DDOS-ing against insure
etcd health check can lead to disk space full due to large log files).
This change was introduced in #11704 .
While we keep the warning logs for etcd health check failures, the
success (or OK) log level should be set to DEBUG.
Fixes #12676
