LoadBalancingClient

class LoadBalancingClient[P <: Protocol] extends WorkerItem with Sender[P, Callback]

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

TODO: does this need to actually be a WorkerItem anymore?
