PR #2267 Introduced support for Zstandard compression. The relevant test expects values for `num_nodes` and `num_producers` based on the (now-incremented) count of compression types.
Passed the affected, previously-failing test:
`ducker-ak test tests/kafkatest/tests/client/compression_test.py`
Reviewers: Jason Gustafson <jason@confluent.io>
In some tests, the check monitoring the JMX tool log output doesn’t quite wait long enough before failing. Increasing the timeout from 10 to 20 seconds.
Removed ignore annotations from the upgrade tests. This PR includes the following changes for updating the upgrade tests:
* Uploaded new versions 0.10.2.2, 0.11.0.3, 1.0.2, 1.1.1, and 2.0.0 (in the associated scala versions) to kafka-packages
* Update versions in version.py, Dockerfile, base.sh
* Added new versions to StreamsUpgradeTest.test_upgrade_downgrade_brokers including version 2.0.0
* Added new versions StreamsUpgradeTest.test_simple_upgrade_downgrade test excluding version 2.0.0
* Version 2.0.0 is excluded from the streams upgrade/downgrade test as StreamsConfig needs an update for the new version, requiring a KIP. Once the community votes the KIP in, a minor follow-up PR can be pushed to add the 2.0.0 version to the upgrade test.
* Fixed minor bug in kafka-run-class.sh for classpath in upgrade/downgrade tests across versions.
* Follow on PRs for 0.10.2x, 0.11.0x, 1.0.x, 1.1.x, and 2.0.x will be pushed soon with the same updates required for the specific version.

Currently, the only way in system tests to add a new variable to the `jaas.conf` template file is to directly edit the path the config is constructed by adding new keyword arguments.
This wasn't necessarily a big problem, since you'd only need edit the `security_config.py` file as JAAS settings should come from the security settings.
Now, with the addition of [KIP-342](https://cwiki.apache.org/confluence/display/KAFKA/KIP-342%3A+Add+support+for+Custom+SASL+extensions+in+OAuthBearer+authentication), the OAuthBearer JAAS config supports arbitrary values in the form of SASL extensions. This patch exposes a more convenient API to overrides these values in system tests.

* Enabled the log cleaner in every system test.
* Removed configs from "kafka.properties" with default values and `socket.receive.buffer.bytes`

The original way of stopping the minikdc process sometimes misfires because the process arg string is very long, and `ps` is not able to find the correct process. Using the `kill_java_processes` method is more reliable for finding and killing java processes.
In system tests, it is useful to have the thread dumps if a broker cannot be stopped using SIGTERM.

1. At the beginning of assign, we first check that all the non-repartition source topics are included in the metadata. If not, we log an error at the leader and set an error in the Assignment userData bytes, indicating that leader cannot complete assignment and the error code would indicate the root cause of it.
2. Upon receiving the assignment, if the error is not NONE the streams will shutdown itself with a log entry re-stating the root cause interpreted from the error code.

Added two additional test cases to quota_test.py, which run between brokers and clients with different throttling behaviors. More specifically,
1. clients with new throttling behavior (i.e., post-KIP-219) and brokers with old throttling behavior (i.e., pre-KIP-219)
2. clients with old throttling behavior and brokers with new throttling behavior

Closes#5294 from jonlee2/kafka-6944
- 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.

Closes#5151 from rhauch/kafka-7009
In BrokerCompatibilityTest.java, when older versioned broker is used (0.10.1, 0.10.2), LIST_OFFSET is not supported as well. Hence in the verification phase, there is a possibility that consumer hit the UnsupportedVersionException earlier than Streams actually hits it:
org.apache.kafka.common.errors.UnsupportedVersionException: The broker does not support LIST_OFFSETS with version in range [2,3]. The supported range is [0,1].
While the test is waiting for
org.apache.kafka.common.errors.UnsupportedVersionException: Cannot create a v0 FindCoordinator request because we require features supported only in 1 or later.
Both are valid errors to expect (the former is from consumer while the latter is from producer of the streams app).

Implementation of [KIP-174](https://cwiki.apache.org/confluence/display/KAFKA/KIP-174+-+Deprecate+and+remove+internal+converter+configs+in+WorkerConfig)
Configuration properties 'internal.key.converter' and 'internal.value.converter'
are deprecated, and default to org.apache.kafka.connect.json.JsonConverter.
Warnings are logged if values are specified for either, or if properties that
appear to configure instances of internal converters (i.e., ones prefixed with
either 'internal.key.converter.' or 'internal.value.converter.') are given.
The property 'schemas.enable' is also defaulted to false for internal
JsonConverter instances (both for keys and values) if it isn't specified.
Documentation and code have also been updated with deprecation notices and
annotations, respectively.
Unit tests have been updated in `PluginsTest` to account for the new defaults for `schemas.enable` for internal key/value converters, and to ensure that (for the time being), internal key/value converters are still configurable despite being deprecated.

* Removed Scala producers, request classes, kafka.tools.ProducerPerformance, encoders,
tests.
* Updated ConsoleProducer to remove Scala producer support (removed `BaseProducer`
and several options that are not used by the Java producer).
* Updated a few Scala consumer tests to use the new producer (including a minor
refactor of `produceMessages` methods in `TestUtils`).
* Updated `ClientUtils.fetchTopicMetadata` to use `SimpleConsumer` instead of
`SyncProducer`.
* Removed `TestKafkaAppender` as it looks useless and it defined an `Encoder`.
* Minor import clean-ups
No new tests added since behaviour should remain the same after these changes.

Closes#5045 from ijuma/kafka-6921-remove-old-producer
test_broker_type_bounce_at_start tries to validate that when the controller is down, the streams client will always fail trying to create the topic; with the current behavior of admin client it is actually not always true: the actual behavior depends on the admin client internals as well as when the controller becomes unavailable during the leader assign partitions phase. I'd suggest at least ignore this test for now until the admin client has more stable (personally I'd even suggest removing this test as its coverage benefits is smaller than its introduced issues to me).
Also adding a few more log4j entries as a result of investigating this issue.

Due to #4644 the consumer connector logs will be much more clean with fewer "broker may not be available" entries. We need to reduce the required frequency from 100 to a smaller number.
I've thought about reducing to just 1, but it may still be transient (i.e. even if broker is starting up you may see a few entries) so I reduced it to 10.

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.

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
