Package config provides decoupling between various configuration sources (etcd, files,...) and the pieces that actually care about them (loadbalancer, proxy).

NewLoadBalancerRR returns a new LoadBalancerRR.

NewProxier returns a new Proxier given a LoadBalancer and an address on which to listen.

LoadBalancerRR is a round-robin load balancer.

Proxier is a simple proxy for TCP connections between a localhost:lport and services that provide the actual implementations.

LoadBalancer is an interface for distributing incoming requests to service endpoints.
