grpc load balancing demo

[kafrax]

var testService = etcdv3.Service{
    Key:   "/addsvc/sum",
    Value: "192.168.102.130:8083",
    TTL:   nil,
}

i use this to register a grpc endpoint to etcd,and use apigateway ask it successful in my project.i need a grpc load balancing demo.

The apigateway example is not meant to be a runnable demo.
