 * Service for assisting communications between controller cluster nodes.

 * Communication via this service is isolated to nodes running a single version of the software. During upgrades, when
 * nodes may be running multiple versions simultaneously, this service prevents nodes running different versions of
 * the software from communicating with each other, thus avoiding compatibility issues. For an equivalent cross-version
 * compatible service, see {@link UnifiedClusterCommunicationService}.
