Consumers are not getting listed in burrow

Nobody has claimed this yet.

I have a dockerized burrow setup to monitor my dev kafka environment. When I check **/v3/kafka/kafka-dev/consumer**, it lists only 2 consumers.

----
"consumers": [
"adept-tracker-atkins",
"burrow-kafka-dev"
],
"request": {
"url": "/v3/kafka/kafka-dev/consumer",
"host": "a9720a5c007a"
}
}
----

But I have 15 consumers in total. All the consumers are committing offsets to kafka. When I restart the burrow container it lists all the consumers but their status will be "NOT FOUND".

----

@toddpalino Can you help me here to get this working. I have to go to production soon.

Start with the /v3/kafka/kafka-dev/consumer endpoint and the consumer.kafka-dev and consumer.kafka-dev_zk sections in burrow.toml. Reproduce the restart behavior and trace how consumer groups are discovered and assigned status; done means all committing consumers are listed without incorrectly showing them as NOT FOUND.
