Corrects the system tests to check for either a 404 or a 409 error and sleeping until the Connect REST API becomes available. This corrects a previous change to how REST extensions are initialized (#6651), which added the ability of Connect throwing a 404 if the resources are not yet started. The integration tests were already looking for 409.

This is the first diff for the implementation of JoinGroup logic for static membership. The goal of this diff contains:
* Add group.instance.id to be unique identifier for consumer instances, provided by end user;
Modify group coordinator to accept JoinGroupRequest with/without static membership, refactor the logic for readability and code reusability.
* Add client side support for incorporating static membership changes, including new config for group.instance.id, apply stream thread client id by default, and new join group exception handling.
* Increase max session timeout to 30 min for more user flexibility if they are inclined to tolerate partial unavailability than burdening rebalance.
* Unit tests for each module changes, especially on the group coordinator logic. Crossing the possibilities like:
6.1 Dynamic/Static member
6.2 Known/Unknown member id
6.3 Group stable/unstable
6.4 Leader/Follower
The rest of the 345 change will be broken down to 4 separate diffs:
* Avoid kicking out members through rebalance.timeout, only do the kick out through session timeout.
* Changes around LeaveGroup logic, including version bumping, broker logic, client logic, etc.
* Admin client changes to add ability to batch remove static members
* Deprecate group.initial.rebalance.delay

This commit creates an EndToEndTest base class which relies on the verifiable consumer. This will ultimately replace ProduceConsumeValidateTest which depends on the console consumer. The advantage is that the verifiable consumer exposes more information to use for validation. It also allows for a nicer shutdown pattern. Rather than relying on the console consumer idle timeout, which requires a minimum wait time, we can halt consumption after we have reached the last acked offsets. This should be more reliable and faster. The downside is that the verifiable consumer only works with the new consumer, so we cannot yet convert the upgrade tests. This commit converts only the replication tests and a flaky security test to use EndToEndTest.
Some Streams system tests have failed during the setup phase
due to the producer having retries disabled and getting some
transient error from the broker.
This patch adds a retries parameter to the VerifiableProducer
(default unchanged), and sets retries to 10 for Streams tests.
It also sets acks equal to the number of brokers for Streams tests.

This is a system test for doing a rolling upgrade of a topology with a named repartition topic.
1. An initial Kafka Streams application is started on 3 nodes. The topology has one operation forcing a repartition and the repartition topic is explicitly named.
2. Each node is started and processing of data is validated
3. Then one node is stopped (full stop is verified)
4. A property is set signaling the node to add operations to the topology before the repartition node which forces a renumbering of all operators (except repartition node)
5. Restart the node and confirm processing records
6. Repeat the steps for the other 2 nodes completing the rolling upgrade
I ran two runs of the system test with 25 repeats in each run for a total of 50 test runs.
All test runs passed

This change adds some basic system tests for delegation token based authentication:
- basic delegation token creation
- producing with a delegation token
- consuming with a delegation token
- expiring a delegation token
- producing with an expired delegation token
New files:
- delegation_tokens.py: a wrapper around kafka-delegation-tokens.sh - executed in container where a secure Broker is running (taking advantage of automatic cleanup)
- delegation_tokens_test.py: basic test to validate the lifecycle of a delegation token
Changes were made in the following file to extend their functionality:
- config_property was updated to be able to configure Kafka brokers with delegation token related settings
- jaas.conf template because a broker needs to support multiple login modules when delegation tokens are used
- consule-consumer and verifiable_producer to override KAFKA_OPTS (to specify custom jaas.conf) and the client properties (to authenticate with delegation token).

This is a new system test testing for optimizing an existing topology. This test takes the following steps
1. Start a Kafka Streams application that uses a selectKey then performs 3 groupByKey() operations and 1 join creating four repartition topics
2. Verify all instances start and process data
3. Stop all instances and verify stopped
4. For each stopped instance update the config for TOPOLOGY_OPTIMIZATION to all then restart the instance and verify the instance has started successfully also verifying Kafka Streams reduced the number of repartition topics from 4 to 1
5. Verify that each instance is processing data from the aggregation, reduce, and join operation
Stop all instances and verify the shut down is complete.
6. For testing I ran two passes of the system test with 25 repeats for a total of 50 test runs.
All test runs passed

KAFKA-7597: Add configurable transaction support to ProduceBenchWorker. In order to get support for serializing Optional<> types to JSON, add a new library: jackson-datatype-jdk8. Once Jackson 3 comes out, this library will not be needed.
Reviewers: Colin McCabe <cmccabe@apache.org>, Ismael Juma <ismael@juma.me.uk>
The Kafka Streams system tests fail with some regularity due to a timeout starting the broker.
The initial start is quite quick, but many of our tests involve stopping and restarting nodes with data already loaded, and also while processing is ongoing.
Under these conditions, it seems to be normal for the broker to take about 25 seconds to start, which makes the 30 second timeout pretty close for comfort.
I have seen many test failures in which the broker successfully started within a couple of seconds after the tests timed out and already initiated the failure/shut-down sequence.

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.

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.

Closes#5456 from wicknicks/error-handling-sys-test
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.

- 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.

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.

This is a general change and is re-requisite to allow streams benchmark test with different streams tests. For the streams benchmark itself I will have a separate PR for switching configs. Details:
1. Create a "streams.properties" file under PERSISTENT_ROOT before all the streams test. For now it will only contain a single config of state.dir pointing to PERSISTENT_ROOT.
2. For all the system test related code, replace the main function parameter of state.dir with propsFilename, then inside the function load the props from the file and apply overrides if necessary.
3. Minor fixes.

Ensures Kafka chroot exists in ZK when starting KafkaService so commands that use ZK and are executed before the first Kafka broker starts do not fail due to the missing chroot.
Also uses chroot with one test that also has security parameterizations so Kafka's test suite exercises these combinations. Previously no tests were exercising chroots.
Changes were validated using sanity_checks which include the chroot-ed test as well as some non-chroot-ed tests.
Some changes required to get the Streams system tests working via Docker
To test:
TC_PATHS="tests/kafkatest/tests/streams" bash tests/docker/run_tests.sh
That command will take about 3.5 hours, and should pass. Note there are a couple of ignored tests.

Currently port forwarding is setup for HttpMetricsCollector when the Service's start_node method is called, but not canceled during stop. This hasn't presented a problem so far because we don't have tests that use this *and* restart the service. However, if a test/service does that, it will throw an exception since the port is already bound.
This just does the cleanup when stopping so a subsequent attempt to start again will succeed.
https://jenkins.confluent.io/job/system-test-kafka-branch-builder/1320 is a test run for a Test that uses ProducerPerformanceService, which in turn uses HttpMetricsCollector to validate the change.
