Serving GRPC gateway and docs on same endpoint

Serving GRPC gateway and docs(swagger) on same endpoint

So idea is pretty simple:

1. We'll create a new httpMux
2. We'll serve runtimeMux on (/)
3. We'll serve index.html (using fileserver) on (/docs/)
4. We'll not forget succeeding "/" on /docs/

In action:

Modify the example pt. 6 in this way:

runtimeMux := runtime.NewServeMux()
...
...  // things to do with runtime mux
...
httpMux := http.NewServeMux()
httpMux.Handle("/", runtimeMux)
prefix := "/docs/"
fileServer := http.FileServer(http.Dir(string("my_docs_folder")))
httpMux.Handle(prefix, http.StripPrefix(prefix, fileServer))
return http.ListenAndServe(":8080", httpMux)

PS: While defining prefix := "/docs/". If you forget putting the "/" in the end. You're gonna waste quite a lot of time wondering what happened!

That's it. Cheers!
