The current approach adds SSL configuration if the advertised listeners includes the string `SSL://`. But in a configuration such as ``` KAFKA_ADVERTISED_LISTENERS: CLIENTS://mykafka.host:9093 KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: CLIENTS:SSL ``` The ssl configuration is not added, even though the protocol `CLIENTS` does map to `SSL` Tweaking this configuration script so that it looks in both `KAFKA_ADVERTISED_LISTENERS` and `KAFKA_LISTENER_SECURITY_PROTOCOL_MAP` for usage of SSL.
