Closes#2558 from cmccabe/KAFKA-4774
More details:
* Replaced `struct` field in Request/Response with a `toStruct` method. This
makes the performance model (including memory usage) easier to understand.
Note that requests have `toStruct()` while responses have `toStruct(version)`.
* Replaced mutable `version` field in `Request.Builder` with an immutable
field `desiredVersion` and a `version` parameter passed to the `build` method.
* Optimised `handleFetchRequest` to avoid unnecessary creation of `Struct`
instances (from 4 to 2 in the worst case and 2 to 1 in the best case).
* Various clean-ups in request/response classes and their test. In particular,
it is now clear what we are testing. Previously, it looked like we were testing
more than we really were.
With this in place, we could remove `AbstractRequest.Builder` in the future by
doing the following:
* Change `AbstractRequest.toStruct` to accept a version (like responses).
* Change `AbstractRequest.version` to be `desiredVersion` (like `Builder`).
* Change `ClientRequest` to take `AbstractRequest`.
* Move validation from the `build` methods to the request constructors or
static factory methods.
* Anything else required for the code to compile again.

This change is in response to [KAFKA-4725](https://issues.apache.org/jira/browse/KAFKA-4725).
When a produce request is received, if the user/client is exceeding their produce quota, the response will be delayed until the quota is refilled appropriately.
Unfortunately, the request body is still referenced in the callback which in turn leaks the messages contained within the request.
This change allows the `KafkaApis` method to take ownership of the request body from the `RequestChannel.Request` object.
I am not sure whether this breaks other invariants which are assumed within other parts of Kafka.

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).

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.
