[DISCUSSION] KAFKA-3633. Kafka Consumer API breaking backward compatibility

[Harsha]

Hi All,
       We noticed KIP-45 broke the compatibility with the consumer API
       that shipped in 0.9.x releases. 
Hugo posted a patch that only adds these old methods back to
KafkaConsumer.java with the deprecated tag. I would like to get this in
0.10 release so that it will help anyone who used new consumer API from
0.9 release.  Anyone has any concerns having this patch in.

Thanks,
-Harsha
