[KAFKA-5212] Consumer ListOffsets request can starve group heartbeats
Through the identification of the poll method in ConsumerCoordinator as the
place where the heartbeat is sent, I modified the metadata so that it polled
periodically every interval for a heartbeat.

> Key: KAFKA-5212
> URL: https://issues.apache.org/jira/browse/KAFKA-5212
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Reporter: Jason Gustafson
> Fix For: 1.1.0, 1.0.1
>
>
> The consumer is not able to send heartbeats while it is awaiting a
> ListOffsets response. Typically this is not a problem because ListOffsets
> requests are handled quickly, but in the worst case if the request takes
> longer than the session timeout, the consumer will fall out of the group.
