> KafkaLog4jAppender is the Log4j Appender to publish messages to Kafka. 
> Since there is no key or explicit partition number, the messages are sent to random partitions. 
> In some cases, it is possible to derive a key from the message itself. 
> So it may be beneficial to enable KafkaLog4jAppender to accept KeyClass which will provide a key for a given message.
