/**
* 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.
*
* 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.
