Agreed - we should add some kind of FailoverLoadBalancer which could
filter errors/exceptions to determine if it should fail over to
another endpoint. (Not all errors/exceptions would be down to a WS
being down - it could be application errors and so forth).
The current LoadBalancer implementations just pick and endpoint to
load to; what we need is another implementation that essentially adds
a custom ErrorHandler to force a redelivery to another endpoint on
certain failures
