/**
 * Task that will add a service to the cluster node. When a service is added
 * in a cluster node the rest of the cluster nodes will need to add a copy.
 * They do -not- need to create database entries for the new service as the originator
 * will have already done that.  This event assumes that it's the default representation
 * of a MUC service, and therefore should not pass information about internal component
 * generated MUC services.
