/**
 * A cluster of load balancers, where configuring the cluster (through the LoadBalancer interface)
 * will configure all load balancers in the cluster.
 * 
 * Config keys (such as LoadBalancer.serverPool and LoadBalancer.urlMappings) are automatically
 * inherited by the children of the load balancer cluster. It is through that mechanism that
 * configuration changes on the cluster will be applied to all child load balancers (i.e. by
 * them all sharing the same serverPool and urlMappings etc).
