Chao Chen 2ae3e82f07 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
