    Cluster: broadcast pong to other slaves in the same ring. · 35820549

    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.
