KAFKA-3418: add javadoc section describing consumer failure detection
----
> Add section on detecting consumer failures in new consumer javadoc

>
> There still seems to be a lot of confusion about the design of the poll()
> loop in regard to consumer liveness. We do mention it in the javadoc, but
> it's a little hidden and we aren't very clear on what the user should do to
> limit the potential for the consumer to fall out of the group (such as
> tweaking max.poll.records). We should pull this into a separate section (e.g.
> Jay suggests "Detecting Consumer Failures") and give it a more complete
> treatment.
