How to implement health checking (readiness, liveness) for pingora server?

[HaoYang670]

Hi, I want to know what is a paradigm to implement readiness and liveness for pingora? What in my mind is I can filter out the health/readliness from path in the proxy service, or I can implement a new http service for health checking. I have no idea which is better, or there are other ways to do this. Thanks
