Cluster: broadcast pong to other slaves in the same ring.
When we schedule a failover, broadcast a PONG to the slaves. The other slaves that plan to get elected will do the same too, this way it is likely that every slave will have a good picture of its own rank. Note that this is N*N messages where N is the number of slaves for the failing master, however usually even large clusters have many master nodes but a limited number of replicas per node, so this is harmless.
