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?

    A Request has been made to shutdown this WorkerItem. By default this will simply unbind the item from its Worker, but this can be overriden to add in custom shutdown behaviors. Be aware that in some cases this method may not be called and the item will be unbound, such as when an IOSystem is shutting down.
