Scenario: 1. Start a cluster with nodes node1, node2, node3 2. Start node4 replacing node node2 3. Stop node node4 after it joined group0 but before it advertised itself in gossip 4. Start node5 replacing node node2 Test simulates the behavior described in #13543. Test passes only if `wait_for_peers_to_enter_synchronize_state` doesn't need to resolve all IPs to return early. If not, node5 will hang trying to resolve the IP of node4: ``` raft_group0_upgrade - : failed to resolve IP addresses of some of the cluster members ([node4's host ID]) ```
