this is here to tell nodes which are still up that the second node went offline. Without that, it will still think that the second node is up.

here we do not wait for other nodes to notice the second one is up, it will be detected on their own when the logic is correct. Until they see the second node JOINED after we started it, they will never select that on their own.

localEndpoints are called localReplicas in 4.0+ and it is a collection of Replicas, not InetAddress(WithPort)
