Closes#3928 from rajinisivaram/KAFKA-5947-auth-failure
This refactor achieves the following:
1. Breaks up the increasingly unmanageable `Protocol` class and moves schemas closer to their actual usage.
2. Removes the need for redundant field identifiers maintained separately in `Protocol` and the respective request/response objects.
3. Provides a better mechanism for sharing common fields between different schemas (e.g. topics, partitions, error codes, etc.).
4. Adds convenience helpers to `Struct` for common patterns (such as setting a field only if it exists).

- reuse decompression buffers in consumer Fetcher
- switch lz4 input stream to operate directly on ByteBuffers
- avoids performance impact of catching exceptions when reaching the end of legacy record batches
- more tests with both compressible / incompressible data, multiple
blocks, and various other combinations to increase code coverage
- fixes bug that would cause exception instead of invalid block size
for invalid incompressible blocks
- fixes bug if incompressible flag is set on end frame block size
Overall this improves LZ4 decompression performance by up to 40x for small batches.
Most improvements are seen for batches of size 1 with messages on the order of ~100B.
We see at least 2x improvements for for batch sizes of < 10 messages, containing messages < 10kB
This patch also yields 2-4x improvements on v1 small single message batches for other compression types.

Closes#2474 from ijuma/kafka-4039-deadlock-during-shutdown
After debugging this i can see the times that it fails there is a race between when the topic is actually created/ready on the broker and when the assignment happens. When it fails `StreamPartitionAssignor.assign(..)` gets called with a `Cluster` with no topics. Hence the test hangs as no tasks get assigned. To fix this I added a `waitForTopics` method to `EmbeddedKafkaCluster`. This will wait until the topics have been created.

If you get a chance can you please take a look at this. I've done the repartitioning in the join, but it results in 2 internal topics for each join. This seems like overkill as sometimes we wouldn't need to repartition at all, others just 1 topic, and then sometimes both, but I'm not sure how we can know that.
I'd also need to implement something similar for leftJoin, but again, i'd like to see if i'm heading down the right path or if anyone has any other bright ideas.
For reference - https://github.com/apache/kafka/pull/1453 - the previous PR

See KIP-31 and KIP-32 for details.
A few notes on the patch:
1. This patch implements KIP-31 and KIP-32. The patch includes features in both KAFKA-3025, KAFKA-3026 and KAFKA-3036
2. All unit tests passed.
3. The unit tests were run with new and old message format.
4. When message format conversion occurs during consumption, the consumer will not be able to detect the message size too large situation. I did not try to fix this because the situation seems rare and only happen during migration phase.

Gradle does not handle subprojects with the same name (top-level tools vs
connect/tools) properly, making the dependency impossible to express correctly
since we need to move the ThroughputThrottler class into the top level tools
project. Moving the current set of tools into the runtime jar works fine since
they are only used for system tests at the moment.

This adds coordination between DistributedHerders using the generalized consumer
support, allowing automatic balancing of connectors and tasks across workers. A
few pieces that require interaction between workers (resolving config
inconsistencies, forwarding of configuration changes to the leader worker) are
incomplete because they require REST API support to implement properly.
