title: GRPC-gateway default healthCheck support
body: <p>I'm using gRPC-gateway that works perfectly fine. But I need to have HealthCheck. I enabled DefaultHealthCheck and it works perfectly. TO make it possible, to check state over HTTP1.1 I found this solution <a href="https://github.com/salrashid123/grpc_health_proxy" rel="nofollow noreferrer">https://github.com/salrashid123/grpc_health_proxy</a>. ANd it works as well. But it's not the best solution to maintain 2 &quot;gateways&quot; + server by it self. So, my qestion is - if there is possible to enable defaultHealthCheck proxying in gRPC gateway?
  BEcause I don't understand how to implement this solution from docs
