class LoadBalancingClient[I, O] extends ServiceClientLike[I, O] with WorkerItem

The LoadBalancingClient will evenly distribute requests across a set of clients. If one client begins failing, the balancer will retry up to numRetries times across the other clients (with each failover hitting different clients to avoid a cascading pileup

Note that the balancer will never try the same client twice for a request, so setting maxTries to a very large number will mean that every client will be tried once
