Another node can stop after it joined the group0 but before it advertised itself in gossip. `get_inet_addrs` will try to resolve all IPs and `wait_for_peers_to_enter_synchronize_state` will loop indefinitely. But `wait_for_peers_to_enter_synchronize_state` can return early if one of the nodes confirms that the upgrade procedure has finished. For that, it doesn't need the IPs of all group 0 members - only the IP of some nodes which can do the confirmation. This pr restructures the code so that IPs of nodes are resolved inside the `max_concurrent_for_each` that `wait_for_peers_to_enter_synchronize_state` performs. Then, even if some IPs won't be resolved, but one of the nodes confirms a successful upgrade, we can continue. Fixes #13543 Closes #14046 * github.com:scylladb/scylladb: raft topology: test: check if aborted node replacing blocks bootstrap raft topology: `wait_for_peers_to_enter_synchronize_state` doesn't need to resolve all IPs
