In the current implementation, it raises an error immediately if a process fails at an ip address.
Why don't all element in addrinfos try to connect at first and throw an exception?
( The current implementation: https://github.com/mysql/mysql-connector-python/blob/403535dbdd45d894c780da23ba96b1a6c81e3866/lib/mysql/connector/network.py#L607 )

For example, if we use the --add-host=localhost:<local-ip-address> option when launch docker container,
it would insert the specified IP address in /etc/hosts.
However, the process connecting to mysql-db using mysql-connector-python fails in the current implementation when accessing 127.0.0.1 (which is usually set up) and the inserted ip adress are not used to access.
