    KAFKA-7111: Log error connecting to node at a higher log level (#5312)
    There are cases where the broker would return an unresolve-able address (e.g broker inside
a docker network while client is outside) and the client would not log any information as
to why it is timing out, since the default log level does not print DEBUG messages.
    Changing this log level will enable easier troubleshooting in such circumstances. This
change does not change the logs shown on transient failures like a broker failure.
