The broker should return NOT_LEADER_FOR_PARTITION for OffsetsForLeaderEpoch requests against non-replicas instead of UNKNOWN_TOPIC_OR_PARTITION. This patch also fixes a minor bug in the handling of ListOffsets request using the DEBUG replica id. We should return UNKNOWN_TOPIC_OR_PARTITION if the topic doesn't exist.

Jacoco 0.8.2 adds Java 11 support:
https://github.com/jacoco/jacoco/releases/tag/v0.8.2
Java 11 RC1 is out so it would be good for us to
get a working CI build.
Author: Ismael Juma <ismael@juma.me.uk>
Reviewers: Dong Lin <lindong28@gmail.com>
Closes#5568 from ijuma/jacoco-0.8.2
Changes:
1. Add org.apache.kafka.streams.processor.internals.metrics.CumulativeCount analogous to Count, but not a SampledStat
2. Use CumulativeCount for -total metrics in streams instead of Count
Testing strategy:
Add a test in StreamsMetricsImplTest which fails on old, incorrect behavior

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.

Sender/RecordAccumulator never resets the next batch expiry time. Its always computed as the min of the current value and the expiry time for all batches being processed. This means that its always set to the expiry time of the first batch, and once that time has passed Sender starts spinning on epoll with a timeout of 0, which consumes a lot of CPU. This patch updates Sender to reset the next batch expiry time on each poll loop so that a new value reflecting the expiry time for the current set of batches is computed.

If the only producer state left in the log is a transaction marker, then we do not know the next expected sequence number. This can happen if there is a call to DeleteRecords which arrives prior to the writing of the marker. Currently we raise an OutOfOrderSequence error when this happens, but this is treated as a fatal error by the producer. Raising UnknownProducerId instead allows the producer to check for truncation using the last acknowledged sequence number and reset if possible.

* Updated TestLogCleaning tool to use Java consumer and rename as LogCompactionTester.
* Enabled the log cleaner in every system test.
* Removed configs from "kafka.properties" with default values and `socket.receive.buffer.bytes`
as the override did not seem necessary.
* Updated `kafka.py` logic to handle duplicates between `kafka.properties` and `server_prop_overrides`.
* Updated Gradle build so that classes from `kafka-clients` test jar can be used in
system tests.

Relative paths in Gradle break when the Gradle daemon is used
unless user.dir can be changed while the process is running.
Java 11 disallows this, so we use project paths instead.
Verified that rat and checkstyle work with Java 11 after these
changes.

Updated two integration tests to use IntegrationTestUtils#waitUntilFinalKeyValueRecordsReceived to eliminate flaky test results.
Also, I updated IntegrationTestUtils#waitUntilFinalKeyValueRecordsReceived method to support having results with the same key present with different values.
For testing, I ran the current suite of streams tests.

1) As titled, add a rewriteTopology that 1) sets application id, 2) maybe disable caching, 3) adjust for source KTable. This optimization can hence be applied for both DSL or PAPI generated Topology.
2) Defer the building of globalStateStores in rewriteTopology so that we can also disable caching. But we still need to build the state stores before InternalTopologyBuilder.build() since we should only build global stores once for all threads.
3) Added withCachingDisabled to StoreBuilder, it is a public API change.
4) [Optional] Fixed unit test config setting functionalities, and set the necessary config to shorten the unit test latency (now it reduces from 5min to 3.5min on my laptop).

We should check TxnOffsetCommit responses for the COORDINATOR_LOADING_IN_PROGRESS error code and retry if we see it. Additionally, if we encounter an abortable error, we need to ensure that pending transaction offset commits are cleared.

Ensure that sends are completed before waiting for channel to be closed based on idle expiry, since channel will not be expired if added to ready keys in the next poll as a result of pending sends.

This PR adds the optimization of eliminating multiple repartition topics when the KStream resulting from a key-changing operation executes other methods using the new key and reduces the repartition topics to one.
Note that this PR leaves in place the optimization for re-using a source topic as a changelog topic for source KTable instances. I'll have another follow-up PR to move the source topic optimization to a method within InternalStreamsBuilder so it can be performed in the same area of the code.
Additionally, the current value of StreamsConfig.OPTIMIZE is all and we'll need to have another KIP to change the value to 2.1.
An integration test RepartitionOptimizingIntegrationTest which asserts the same results for an optimized topology with one repartition topic as the un-optimized version with four repartition topics.

Closes#5221 from radai-rosenblatt/metadata-adventures
Pre-initialization of clients in IntegrationTestHarness is a cause of significant confusion and has resulted in a bunch of inconsistent client creation patterns. This patch requires test cases to create needed clients explicitly and makes the creation logic more consistent.
