The table of (stateless) transformations uses the transformation name in the first column and a description in the second column. I adjusted the transformation name for FlatMapValues accordingly.

Right now, we have scattered uses of `SerDes` throughout the docs. These should be updated to be `Serdes`, as that's what we commonly use now.

We removed default 24 hours grace period in KIP-633, and deprecate some grace methods, but we forgot to update the stream docs.

Code samples are now unified and correctly formatted.
Samples under Streams use consistently the prism library.

Implements KIP-418, that deprecated the `branch()` operator in favor of the newly added and type-safe `split()` operator.

During the AK website upgrade, changes made to kafka-site weren't migrated back to kafka-docs.
This PR is an attempt at porting the streams changes to kafka/docs
For the most part, the bulk of the changes in the PR are cosmetic.

Add necessary documentation for KIP-450, adding sliding window aggregations to KStreams
Reviewers: A. Sophie Blee-Goldman <sophie@confluent.io>, Guozhang Wang <wangguoz@gmail.com>
Wildcard import of the old org.apache.kafka.streams.scala.Serdes leads
to a name clash because some of implicits has the same names as types
from the scala's std lib. The new oak.streams.scala.serialization.Serdes is
the same as the old Serdes, but without name clashes.
The old one is marked as deprecated.
Also, add missing serdes for UUID, ByteBuffer and Short types in
the new Serdes.
Implements: KIP-616

- allows to add and connect state stores to processors/transformers implicitly

* Minor: Some html fixes Streams DSL documentation:
- duplicate id
- duplicate opening <span> element
- surplus closing </div> tag
* Replaced opening/closing quotation mark codes with " (they caused w3c validation to complain).
* Replaced right arrow that wasn't rendered correctly with →

Currently, tumbling windows are defined as "a special case of hopping time windows" in the streams docs, but hopping windows are only explained in a subsequent section.
I think it would make sense to switch the order of these paragraphs around. To me this also makes more sense semantically.
Testing
Built the site and checked that everything looks ok and html is valid (or at least didn't contain any new warnings that were caused by this change).

* Adjust build and documentation.
* Use lambda syntax for SAM types in `core`, `streams-scala` and
`connect-runtime` modules.
* Remove `runnable` and `newThread` from `CoreUtils` as lambda
syntax for SAM types make them unnecessary.
* Remove stale comment in `FunctionsCompatConversions`,
`KGroupedStream`, `KGroupedTable' and `KStream` about Scala 2.11,
the conversions are needed for Scala 2.12 too.
* Deprecate `org.apache.kafka.streams.scala.kstream.Suppressed`
and use `org.apache.kafka.streams.kstream.Suppressed` instead.
* Use `Admin.create` instead of `AdminClient.create`. Static methods
in Java interfaces can be invoked since Scala 2.12. I noticed that
MirrorMaker 2 uses `AdminClient.create`, but I did not change them
as Connectors have restrictions on newer client APIs.
* Improve efficiency in a few `Gauge` implementations by avoiding
unnecessary intermediate collections.
* Remove pointless `Option.apply` in `ZookeeperClient`
`SessionState` metric.
* Fix unused import/variable and other compiler warnings.
* Reduce visibility of some vals/defs.

* Revert "MINOR: Add unit test for SerDe auto-configuration (#6610)"
This reverts commit 172fbb2dd5.
* Revert "[KAFKA-3729] Auto-configure non-default SerDes passed alongside the topology builder (#6461)"
This reverts commit e56ebbffca.
The two merged PRs introduce a breaking change. Reverting to preserve backward compatibility. Jira ticket reopened.

Scala 2.12 has better support for newer Java versions and includes additional
compiler warnings that are helpful during development. In addition, Scala 2.11
hasn't been supported by the Scala community for a long time, the soon to be
released Spark 2.4.0 will finally support Scala 2.12 (this was the main reason
preventing many from upgrading to Scala 2.12) and Scala 2.13 is at the RC stage.
It's time to start recommending the Scala 2.12 build as we prepare support for
Scala 2.13 and start thinking about removing support for Scala 2.11.
In the meantime, Jenkins will continue to build all supported Scala versions (including
Scala 2.11) so the PR and trunk jobs will fail if people accidentally use methods
introduced in Scala 2.12.
