This change mainly have 2 components:
1. extend the existing transactions_test.py to also try out new sendTxnOffsets(groupMetadata) API to make sure we are not introducing any regression or compatibility issue
a. We shrink the time window to 10 seconds for the txn timeout scheduler on broker so that we could trigger expiration earlier than later
2. create a completely new system test class called group_mode_transactions_test which is more complicated than the existing system test, as we are taking rebalance into consideration and using multiple partitions instead of one. For further breakdown:
a. The message count was done on partition level, instead of global as we need to visualize
the per partition order throughout the test. For this sake, we extend ConsoleConsumer to print out the data partition as well to help message copier interpret the per partition data.
b. The progress count includes the time for completing the pending txn offset expiration
c. More visibility and feature improvements on TransactionMessageCopier to better work under either standalone or group mode.

Do not initialize `JmxTool` by default when running console consumer. In order to support this, we remove `has_partitions_assigned` and its only usage in an assertion inside `ProduceConsumeValidateTest`, which did not seem to contribute much to the validation.

In some system tests a Streams app is started and then prints a message to stdout, which the system test waits for to confirm the node has successfully been brought up. It then greps for certain log messages in a retriable loop.
But waiting on the Streams app to start/print to stdout does not mean the log file has been created yet, so the grep may return an error. Although this occurs in a retriable loop it is assumed that grep will not fail, and the result is piped to wc and then blindly converted to an int in the python function, which fails since the error message is a string (throws ValueError)
We should catch the ValueError and return a 0 so it can try again rather than immediately crash

The upgrade system test correctly rolls by upgrading the broker and
leaving the IBP, and then rolling again with the latest IBP version.
Unfortunately, this is not sufficient to pick up many problems in our IBP
gating as we charge through the rolls and after the second roll all of
the brokers will rejoin the ISR and the test will be treated as a
success.
This test adds two new checks:
1. We wait for the ISR to stabilize for all partitions. This is best
practice during rolls, and is enough to tell us if a broker hasn't
rejoined after each roll.
2. We check the broker logs for some common protocol errors. This is a
fail safe as it's possible for the test to be successful even if some
protocols are incompatible and the ISR is rejoined.

Recently, system tests test_rebalance_[simple|complex] failed
repeatedly with a verfication error. The cause was most probably
the missing clean-up of a state directory of one of the processors.
A node is cleaned up when a service on that node is started and when
a test is torn down.
If the clean-up flag clean_node_enabled of a EOS Streams service is
unset, the clean-up of the node is skipped.
The clean-up flag of processor1 in the EOS tests should stay set before
its first start, so that the node is cleaned before the service is started.
Afterwards for the multiple restarts of processor1 the cleans-up flag should
be unset to re-use the local state.
After the multiple restarts are done, the clean-up flag of processor1 should
again be set to trigger node clean-up during the test teardown.
A dirty node can lead to test failures when tests from Streams EOS tests are
scheduled on the same node, because the state store would not start empty
since it reads the local state that was not cleaned up.

When Trogdor wants to clear all the faults injected to Kibosh, it sends the empty JSON object {}. However, Kibosh expects {"faults":[]} instead. Kibosh should handle the empty JSON object, since that's consistent with how Trogdor handles empty JSON fields in general (if they're empty, they can be omitted). We should also have a test for this.

Closes#7477 from cmccabe/KAFKA-8984
The consumer's `committed` API does not return an entry in the response map for a requested partition if there is no committed offset. The transactional message copier, which is used in the transaction system test, did not account for this. If the first transaction attempted by the copier was randomly aborted, then we would not seek to the beginning as expected, which means we would fail to copy some of the records.
This patch fixes the problem by iterating over the assignment rather than the result of `committed` when resetting offsets. It also adds enables additional logging in the transaction message copier service to make finding problems easier in the future.

Inside onLeavePrepare we would look into the assignment and try to revoke the owned tasks and notify users via RebalanceListener#onPartitionsRevoked, and then clear the assignment.
However, the subscription's assignment is already cleared in this.subscriptions.unsubscribe(); which means user's rebalance listener would never be triggered. In other words, from consumer client's pov nothing is owned after unsubscribe, but from the user caller's pov the partitions are not revoked yet. For callers like Kafka Streams which rely on the rebalance listener to maintain their internal state, this leads to inconsistent state management and failure cases.
Before KIP-429 this issue is hidden away since every time the consumer re-joins the group later, it would still revoke everything anyways regardless of the passed-in parameters of the rebalance listener; with KIP-429 this is easier to reproduce now.
Our fixes are following:
• Inside unsubscribe, first do onLeavePrepare / maybeLeaveGroup and then subscription.unsubscribe. This we we are guaranteed that the streams' tasks are all closed as revoked by then.
• [Optimization] If the generation is reset due to fatal error from join / hb response etc, then we know that all partitions are lost, and we should not trigger onPartitionRevoked, but instead just onPartitionsLost inside onLeavePrepare. This is because we don't want to commit for lost tracks during rebalance which is doomed to fail as we don't have any generation info.

All four flavors of the repartition/optimization tests have been reported as flaky and failed in one place or another:
* RepartitionOptimizingIntegrationTest.shouldSendCorrectRecords_OPTIMIZED
* RepartitionOptimizingIntegrationTest.shouldSendCorrectRecords_NO_OPTIMIZATION
* RepartitionWithMergeOptimizingIntegrationTest.shouldSendCorrectRecords_OPTIMIZED
* RepartitionWithMergeOptimizingIntegrationTest.shouldSendCorrectRecords_NO_OPTIMIZATION
They're pretty similar so it makes sense to knock them all out at once. This PR does three things:
* Switch to in-memory stores wherever possible
* Name all operators and update the Topology accordingly (not really a flaky test fix, but had to update the topology names anyway because of the IM stores so figured might as well)
* Port to TopologyTestDriver -- this is the "real" fix, should make a big difference as these repartition tests required multiple roundtrips with the Kafka cluster (while using only the default timeout)

Small follow-up to trunk PR #7423
While debugging the 2.3 VP PR we realized we should remove the leader-tracking from the VP system test altogether. We'd already merged the corresponding trunk PR so I made a quick new PR for trunk (also fixes a missed version bump in one of the log messages)

Implemented KIP-507 to secure the internal Connect REST endpoints that are only for intra-cluster communication. A new V2 of the Connect subprotocol enables this feature, where the leader generates a new session key, shares it with the other workers via the configuration topic, and workers send and validate requests to these internal endpoints using the shared key.
Currently the internal `POST /connectors/<connector>/tasks` endpoint is the only one that is secured.
This change adds unit tests and makes some small alterations to system tests to target the new `sessioned` Connect subprotocol. A new integration test ensures that the endpoint is actually secured (i.e., requests with missing/invalid signatures are rejected with a 400 BAD RESPONSE status).

Instead of sending the leader's version and having older members try to blindly upgrade.
The only other real change here is that we will also set the VERSION_PROBING error code and return early from onAssignment when we are upgrading our used subscription version (not just downgrading it) since this implies the whole group has finished the rolling upgrade and all members should rejoin with the new subscription version.
Also piggy-backing on a fix for a potentially dangerous edge case, where every thread of an instance is assigned the same set of active tasks.

This change adds a command line option to the `ducker-ak up' command to enable exposing ports from docker containers. The exposed ports will be mapped to the ephemeral ports on the host. The option is called `expose-ports' and can take either a single value (like 5005) or a range (like 5005-5009). This port will then exposed from each docker container that ducker-ak sets up.
