The service takes a JSON payload containing either an "id" or a "name" field. "id" disconnects the client connection id, "name" disconnects _all_ of the clients connected to the server with that name. - `$SYS.REQ.SERVER.%s.LDM` (where %s is the server_id) and takes a JSON payload containing either an "id" or a "name" field. "id" sends an LDM Info message to the client connection id, "name" sends an LDM Info message to _all_ of the clients connected to the server with that name. This features allow administrators to manually 're-balance' client connections between the servers in the cluster (e.g. after a rolling upgrade of the servers where one server ends up with no client connections after the upgrade), by kicking some of the client connections from one of the 'overloaded' (in comparison to other servers) servers in the cluster, causing them to re-estalibsh their connection to (hopefully) another server.
