gRPC client side load balancing example using Go

This is a gRPC client-side load balancing example on top of grpc-go.

The only load balancer bundled to grpc-go is grpc.RoundRobin. grpc RoundRoubin requires a grpc.Resolver which is intended to implement a DNS resolver or an other resourse resolution mechanism like Consul.

In this example I implemented a grpc.Resolver which only returns fixed servers initially passed. It is good for trying gRPC load balancing instantly.
