KAFKA-2769: Multi-consumer integration tests for consumer assignment incl.
session timeouts and corresponding fixes
-- Refactored multi-consumer integration group assignment validation tests
for round-robin assignment
-- Added multi-consumer integration tests for session timeout expiration:
1. When a consumer stops polling
2. When a consumer calls close()
-- Fixes to issues found with session timeout expiration tests woth help
from Jason Gustafson: Try to avoid SendFailedException exception by cancelling
the scheduled tasks and ensuring metadata update before sending group leave
requests + send leave group request with retries.

1. shouldKeepMemberAlive(): when we are in the sync phase, we do want
to expire members if we don't get any response
2. Try to avoid SendFailedException exception by cancelling the
scheduled tasks and ensuring metadata update before sending group leave
requests.

> Integration tests for multi-consumer assignment including session timeouts

> Key: KAFKA-2769

> Project: Kafka
> Issue Type: Test
> Reporter: Anna Povzner
> Assignee: Anna Povzner
>
> We currently don't have integration tests for multi-consumer range assignment
> and session timeout expiration scenarios.
> This card is to add multi-consumer integration tests for range assignment:
> -- initial assignment
> -- adding a new consumer to an existing group
> -- adding and removing a topic to/from subscription
> -- session timeout expiration when consumer stops polling and on consumer
> close().
