Closes#4007 from ijuma/java-9-version-handling-improvements
Added Connect metrics specific to source tasks, and builds upon #3864 and #3911 that have already been merged into `trunk`, and #3959 that has yet to be merged.
I'll rebase this PR when the latter is merged.

Closes#3975 from rhauch/kafka-5902
This PR improves the output format of DumpLogSegments when the `--offset-decoder` option is used for consuming `__consumer_offsets`, especially when it comes to group metadata.
An example of the partial output with existing formatting:
```
key: metadata::console-consumer-40190 payload: consumer:range:1:{consumer-1-20240b92-fbf4-44d5-bf8c-66b6d70c9948=[foo-0]}
```
An example of the same output with suggested formatting:
```
key: {"metadata":"console-consumer-40190"} payload: {"protocolType":"consumer","protocol":"range","generationId":1,"assignment":"{consumer-1-20240b92-fbf4-44d5-bf8c-66b6d70c9948=[foo-0]}"}

Closes#4005 from mjsax/minor-fix-javadoc-warnings
We log a warning instead, which is what we also do if the partition
hasn't been created yet.
A few other improvements:
- Return updated high watermark if fetch is returned immediately.
This seems to be more intuitive and is consistent with the case
where the fetch request is served from the purgatory.
- Centralise offline partition handling
- Remove unnecessary `tryCompleteDelayedProduce` that would
already have been done by the called method
- A few other minor clean-ups

Closes#3996 from ijuma/avoid-exception-in-measurable-value
Replaces the static `RequestMetrics` object with a class so that metrics
are created and removed during broker startup and shutdown to avoid metrics
tests being affected by metrics left behind by previous tests.
Also reinstates `kafka.api.MetricsTest` which was failing frequently earlier
due to tests removing the static request metrics.

Closes#3991 from rajinisivaram/KAFKA-5968
When logging is disabled and there are state stores the task never transitions from restoring to running. This is because we only ever check if the task has state stores and return false on initialization if it does. The check should be if we have changelog partitions, i.e., we need to restore.

Closes#3959 from rhauch/kafka-5901
The `metric.reporters` description in the documentation says to implement the `MetricReporter` class, but the actual class is `MetricsReporter`. [MetricsReporter.java](https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/metrics/MetricsReporter.java)
The configurations documentation is also inconsistent as some references to classes do not have the full package name while others do.

Instead of having the metrics registry and the
org.apache.kafka.common.metrics.Metrics object be separate things,
have the metrics registry hold a copy of the Metrics object.
That way, all the metricInstance stuff is hidden, and we don't
have to make sure that the metrics registry and the Metrics
object are configured identicailly (with the same tags).
I personally think this looks a little better.

2. The merge() method in KStreamBuilder was changed so that it would use the single variable argument
rather than several variable arguments in the KStreamImpl implementation
3. The merge() method in KStream has been declared as final and tests have been added to test correctness.

Closes#3950 from manjuapu/customer-logo-stream
Offset and partition are not converted from String to
long and int correctly.
Running the command line with --from-file option causes
the following exception:
java.lang.ClassCastException: java.lang.String cannot be
cast to java.lang.Integer
Reason: asInstanceOf used for the conversion.
Also, unit test is using --to-earliest and --from-file
together when executing the test. This is executing
--to-earliest option only and ignoring --from-file
option. Since the preparation part is also using
--to-earliest to create the file, this unit test
passes without testing --from-file option. Fixed
the unit test too.
