/**
 * Task to be requested by a node that joins a cluster and be executed in the senior cluster member to get
 * the services with rooms with occupants. The list of services with rooms with occupants is returned to
 * the new cluster node so that the new cluster node can be updated and have the same information shared
 * by the cluster.<p>
 *
 * Moreover, each existing cluster node will also need to learn the services and rooms with occupants that
 * exist in the new cluster node and replicate them. This work is accomplished using
 * {@link GetNewMemberRoomsRequest} on each service.
