- Removed Scala consumers (`SimpleConsumer` and `ZooKeeperConsumerConnector`)
and their tests.
- Removed Scala request/response/message classes.
- Removed any mention of new consumer or new producer in the code
with the exception of MirrorMaker where the new.consumer option was
never deprecated so we have to keep it for now. The non-code
documentation has not been updated either, that will be done
separately.
- Removed a number of tools that only made sense in the context
of the Scala consumers (see upgrade notes).
- Updated some tools that worked with both Scala and Java consumers
so that they only support the latter (see upgrade notes).
- Removed `BaseConsumer` and related classes apart from `BaseRecord`
which is used in `MirrorMakerMessageHandler`. The latter is a pluggable
interface so effectively public API.
- Removed `ZkUtils` methods that were only used by the old consumers.
- Removed `ZkUtils.registerBroker` and `ZKCheckedEphemeral` since
the broker now uses the methods in `KafkaZkClient` and no-one else
should be using that method.
- Updated system tests so that they don't use the Scala consumers except
for multi-version tests.
- Updated LogDirFailureTest so that the consumer offsets topic would
continue to be available after all the failures. This was necessary for it
to work with the Java consumer.
- Some multi-version system tests had not been updated to include
recently released Kafka versions, fixed it.
- Updated findBugs and checkstyle configs not to refer to deleted
classes and packages.

There are a couple minor additions in this PR:
1. Add a new test for window store, to range query upon receiving each record.
2. In the non-windowed state store case, add a get call before the put call.
3. Enable caching by default to be consistent with other Join / Aggregate cases, where caching is enabled by default.

SimpleBenchmark:
1.a Do not rely on manual num.records / bytes collection on atomic integers.
1.b Rely on config files for num.threads, bootstrap.servers, etc.
1.c Add parameters for key skewness and value size.
1.d Refactor the tests for loading phase, adding tumbling-windowed count.
1.e For consumer / consumeproduce, collect metrics on consumer instead.
1.f Force stop the test after 3 minutes, this is based on empirical numbers of 10M records.
Other tests: use config for kafka bootstrap servers.
streams_simple_benchmark.py: only use scale 1 for system test, remove yahoo from benchmark tests.
Note that the JMX based metrics is more accurate than the manually collected metrics.

1. Use JmxMixin for SimpleBenchmark (will remove the self reporting in #4744), only when loading phase is false (i.e. we are in fact starting the streams app).
2. Reported the full jmx reported metrics in log files, and in the returned data only return the max values: this is because we want to skip the warming up and cooling down periods that will have lower rate numbers, while max represents the actual rate at full speed.
3. Incorporates two other improves to JMXTool: #1241 and #2950

We are occasionally hitting some timeouts due to processing not finishing. So rather than failing the build for these reasons it would be better to reduce the runtime.

Closes#3725 from dguy/fix-system-test
The log_level parameter is used in system tests in kafka.py. However the log4j template accepted that parameter in only one place. This led to a large number of DEBUG lines printed even when the intention was to capture only INFO lines. Led to huge log files. Thanks to ijuma for noticing this.

Closes#3247 from enothereska/minor-log4j-template-fix
- Improves streams efficiency by more than 200K requests/second (small 100 byte requests)
- Gets streams efficiency very close to pure consumer (see results in https://jenkins.confluent.io/job/system-test-kafka-branch-builder/746/console)
- Maintains same fairness across tasks
- Schedules all records in the queue in-between poll() calls, not just one per task.

Closes#2643 from enothereska/minor-schedule-round-robin
There were some minor differences in the basic consumer config and streams config that are now rectified. In addition, in AWS environments the socket size makes a big difference to performance and I've tuned it up accordingly. I've also increased the number of records now that perf is higher.

Closes#2634 from enothereska/minor-standardize-params
This PR fixes a blocker issue, where the streams client code cannot talk to the controller. It also enables a system test that was previously failing.
This PR is for trunk only. A separate PR with just the fix (but not the tests) will be created for 0.10.2.

This patch adds logic for the following:
- remove hard-coded paths to various scripts and jars in kafkatest service classes
- provide a mechanism for overriding path resolution logic with a "pluggable" path resolver class

Closes#1245 from granders/configurable-install-path
* Use a fixed `Random` seed in `EndToEndLatency.scala` for determinism
* Add `compression_type` to and remove `consumer_fetch_max_wait` from `end_to_end_latency.py`. The latter was never used.
* Tweak logging of `end_to_end_latency.py` to be similar to `consumer_performance.py`.
* Add `compression_type` to `benchmark_test.py` methods and add `snappy` to `matrix` annotation
* Use randomly generated bytes from a restricted range for `ProducerPerformance` payload. This is a simple fix for now. It can be improved in the PR for KAFKA-3554.
