As title suggested, we boost 3 stream instances stream job with one minute session timeout, and once the group is stable, doing couple of rolling bounces for the entire cluster. Every rejoin based on restart should have no generation bump on the client side.

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 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

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.

This PR does the following:
* Remove the StreamsRepeatingIntegerKeyProducerService and the associated Java class

* Update the corresponding Python file verifiable_producer.py to support the new parameter.

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

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.

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.

System test for two cases:
* Starting a multi-node streams application with the broker down initially, broker starts and confirm rebalance completes and streams application still able to process records.
* Multi-node streams app running, broker goes down, stop stream instance(s) confirm after broker comes back remaining streams instance(s) still function.

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.
