The logging messages is too verbose when starting or shutting down.

The following logging messages is too verbose. I just did start a server and then did shutdown it.

What I suggest is only to show a starting logging message with address info in INFO level when starting like:

Succeeded to start rpc server on 127.0.0.1:10001.

Other logging messages should be debug level.

If you guys think it's appropriate to do this, I'd like to request a PR to refine it.
