Getting consumers list from Kafka Metadata API

Hi guys,

I was wondering if I could get a list of consumers / consumer groups from
Kafka directly without the use of Zookeeper?

Bonus point goes if I can get a list of producers too?

I'm currently working on a little monitoring tool for Kafka 0.8 (
https://github.com/mofirouz/kafka-monitor). Hope that could be useful.

Cheers,
Mo.
