There is a slight change of behaviour: we now complete the `Future` returned from `send`
before the callbacks are invoked. This seems OK and perhaps a little better as the `Future`
can make progress sooner (as it would typically be blocked on a different thread than the
I/O thread that invokes the callbacks).

Closes#2398 from enothereska/hotfix-streams-metrics
Found a few recently added unit tests did not close KStreamTestDriver after the test itself is closed; this can cause RocksDB virtual function called if the contained topology has some persistent store since they will be initialized but not closed in time.
MINOR fix: found that when closing KStreamTestDriver, we need to first flushing all stores before closing any of them; this is triggered from the `KTableKTableLeftJoin.shouldNotThrowIllegalStateExceptionWhenMultiCacheEvictions`.
MINOR fix: in CachingXXXStore, the `name` field is actually used as the cache's namespace, not really the store name or its corresponding topic name. Fixed it by renaming it to `cacheName` and use `this.name()` elsewhere which will call the underlying store's name.

Closes#2425 from noslowerdna/KAFKA-4687
The root cause of this issue is that in InternalTopicManager we are creating topics one-at-a-time, and for this test, there are 31 topics to be created, as a result it is possible that the consumer could time out during the assignment in rebalance, and the next leader has to do the same again because of "makeReady" calls are one-at-a-time.
This patch batches the topics into a single create request and also use the StreamsKafkaClient directly to fetch metadata for validating the created topics. Also optimized a bunch of inefficient code in InternalTopicManager and StreamsKafkaClient.
Minor cleanup: make the exception message more informative in integration tests.

1. In StreamThread, always use subscribe(Pattern, ..) function in order to avoid sending MetadataRequest with specific topic names and cause brokers to possibly auto-create subscribed topics; the pattern is generated as "topic-1|topic-2..|topic-n".
2. In ConsumerCoordinator, let the leader to refresh its metadata if the generated assignment contains some topics that is not contained in the subscribed topics; also in SubscriptionState, modified the verification for regex subscription to against the regex pattern instead of the matched topics since the returned assignment may contain some topics not yet created when joining the group but existed after the rebalance; also modified some unit tests in `KafkaConsumerTest` to accommodate the above changes.
3. Minor cleanup: changed String[] to List<String> to avoid overloaded functions.
4. Minor cleanup: enforced strong typing in SinkNodeFactory and removed unnecessary unchecked tags.
5. Minor cleanup: augmented unit test error message and fixed a potential transient failure in KafkaStreamTest.

Variance changes introduced in KIP-100 cause compilation failures with lambda expression in Java 8. To my knowledge this only affects the following method
`KStreams.transform(TransformerSupplier<...>, String...)`
prior to the changes it was possible to write:
`streams.transform(MyTransformer::new)`
where `MyTransformer` extends `Transformer`
After the changes the Java compiler is unable to infer correct return types for the lambda expressions. This change fixed this by reverting to invariant return types for transformer suppliers.
please cherry-pick into 0.10.2.x

ZK removed reveal a bug in `StreamPartitionAssigner` but did not fix it properly. This is a follow up bug fix.
Issue:
- If topic metadata is missing, `StreamPartitionAssigner` should not create any affected tasks that consume topics with missing metadata.
- Depending downstream tasks should not be create either.
- For tasks that are not created, no store changelog topics (if any) should get created
- For tasks that write output to not-yet existing internal repartitioning topics, those repartitioning topics should not get created

Current implementation of ProducerPerformance creates static payload. This is not very useful in testing compression or when you want to test with production/custom payloads. So, we decided to add support for providing payload file as an input to producer perf test script.
We made the following changes:
1. Added support to provide a payload file which can have the list of payloads that you actually want to send.
2. Moved payload generation inside the send loop for cases when payload file is provided.
Following are the changes to how the producer-performance is evoked:
1. You must provide "--record-size" or "--payload-file" but not both. This is because, record size cannot be guaranteed when you are using custom events.
e.g. ./kafka-producer-perf-test.sh --topic test_topic --num-records 100000 --producer-props bootstrap.servers=127.0.0.1:9092 acks=0 buffer.memory=33554432 compression.type=gzip batch.size=10240 linger.ms=10 --throughput -1 --payload-file ./test_payloads --payload-delimiter ,
2. Earlier "--record-size" was a required config, now you must provide exactly one of "--record-size" or "--payload-file". Providing both will result in an error.
3. Support for an additional parameter "--payload-delimiter" has been added which defaults to "\n"

Issue: https://issues.apache.org/jira/browse/KAFKA-4614
Fixes the problem that the broker threads suffered by long GC pause.
When GC thread collects mmap objects which were created for index files, it unmaps memory mapping so kernel turns to delete a file physically. This work may transparently read file's metadata from physical disk if it's not available on cache.
This seems to happen typically when we're using G1GC, due to it's strategy to left a garbage for a long time if other objects in the same region are still alive.
See the link for the details.
