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

Introduce List serde for primitive types or custom serdes with a serializer and a deserializer according to KIP-466

Deprecates the following
1. StreamsConfig.EXACTLY_ONCE
2. StreamsConfig.EXACTLY_ONCE_BETA
3. Producer#sendOffsetsToTransaction(Map offsets, String consumerGroupId)
And introduces a new StreamsConfig.EXACTLY_ONCE_V2 config. Additionally, this PR replaces usages of the term "eos-beta" throughout the code with the term "eos-v2"

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.

Currently, the source reference are all pointing to the 1.0 version codes,
which is obviously wrong. Update to the current dotVersion.

Add necessary documentation for KIP-450, adding sliding window aggregations to KStreams

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
Reviewers: John Roesler <vvcephei@apache.org>
- part of KIP-572
- removed the usage of `retries` in `GlobalStateManger`
- instead of retries the new `task.timeout.ms` config is used
Reviewers: John Roesler <john@confluent.io>, Boyang Chen <boyang@confluent.io>, Guozhang Wang <guozhang@confluent.io>
Add docs for KIP-441 and KIP-613.
Fixed some miscellaneous unrelated issues in the docs:
* Adds some missing configs to the Streams config docs: max.task.idle.ms,topology.optimization, default.windowed.key.serde.inner.class, and default.windowed.value.serde.inner.class
* Defines the previously-undefined default windowed serde class configs, including choosing a default (null) and giving them a doc string, so the yshould nwo show up in the auto-generated general Kafka config docs
* Adds a note to warn users about the rocksDB bug that prevents setting a strict capacity limit and counting write buffer memory against the block cache

Implements KIP-401:
- Add ConnectedStoreProvider interface
- let Processor/[*]Transformer[*]Suppliers extend ConnectedStoreProvider
- 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).

Added re-direct for new page and added link to Developer Guide page
Reviewers: Matthias J. Sax <mjsax@apache.org>, Sophie Blee-Goldman <sophie@confluent.io>,
* 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.
