LoadBalancingClient
Attempt to bind this WorkerItem to the worker.
Attempt to bind this WorkerItem to the worker. When the binding succeeds,
onBind() is called and the item will be able to receive events and
messages. Notice that this method is asynchronous.
The worker to bind to
When bound to a worker, this contains the [WorkerItemBinding]

TODO: There is probably room to generalize some of this plumbing
Unbinds the WorkerItem, if it is bound.
Unbinds the WorkerItem, if it is bound. When unbinding is complete,
onUnbind() is called. This method is asynchronous.
Updates the client list, creating connections for new addresses not in the existing list and closing connections not in the new list
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
