KAFKA-3993 Console Producer Drops Data
@ijuma Would you mind taking a look?
This fixes the problem for me using this test script.
```
export BOOTSTRAP_SERVERS=localhost:9092
export TOPIC=bar
export MESSAGES=10000
./bin/kafka-topics.sh --zookeeper localhost:2181 --create --partitions 1
--replication-factor 1 --topic "$TOPIC" \
&& echo "acks=all" > /tmp/producer.config \
&& echo "linger.ms=0" >> /tmp/producer.config \
&& seq "$MESSAGES" | ./bin/kafka-console-producer.sh --broker-list
"$BOOTSTRAP_SERVERS" --topic "$TOPIC" \
&& ./bin/kafka-console-consumer.sh --bootstrap-server "$BOOTSTRAP_SERVERS"
--new-consumer --from-beginning --max-messages "${MESSAGES}" --topic "$TOPIC"
```

> Affects Versions: 0.10.0.0

>
> The console producer drops data when if the process exits too quickly. I
> suspect that the shutdown hook does not call close() or something goes wrong
> during that close().
