This change allows for testing custom Processors and Transformers that call `schedule` and `commit` using KStreamTestDriver, by _not_ throwing `UnsupportedOperationException`.
This PR is my original work.

Closes#4002 from dguy/restore
Without this patch, if the replica's log was somehow truncated before
the leader's, it is possible for the replica fetcher thread to
continuously throw an OutOfOrderSequenceException because the
incoming sequence would be non-zero and there is no local state.
This patch changes the behavior so that the replica state is updated to
the leader's state if there was no local state for the producer at the
time of the append.

For record conversion tests, check time >=0 since conversion times may be too small to be measured accurately. Since default value is -1, the test is still useful. Also increase message size in SslTransportLayerTest#testNetworkThreadTimeRecorded to avoid failures when processing time is too small.

Closes#3862 from joel-hamill/joel-hamill/streams-dev-guide
A new mechanism was added recently to the Metrics framework to make it easier to generate the documentation. It uses a registry with a MetricsNameTemplate for each metric, and then those templates are used when creating the actual metrics. The metrics framework provides utilities that can generate the HTML documentation from the registry of templates.
This change moves the recently-added Connect metrics over to use these templates and to then generate the metric documentation for Connect.
This PR is based upon #3975 and can be rebased once that has been merged.

Minor change to approximateNumEntries() method in CompositeReadOnlyKeyValueStore class.

total += store.approximateNumEntries();
}
return total < 0 ? Long.MAX_VALUE : total;
The check for negative value seems to account for wrapping. However, wrapping can happen within the for loop. So the check should be performed inside the loop.

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:
```

```
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]}"}

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

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.
