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.
Reviewers: John Roesler <vvcephei@apache.org>
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
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
Reviewers: Bruno Cadonna <bruno@confluent.io>, John Roesler <vvcephei@apache.org>
Implements KIP-401:
- Add ConnectedStoreProvider interface
- let Processor/[*]Transformer[*]Suppliers extend ConnectedStoreProvider
- allows to add and connect state stores to processors/transformers implicitly
Reviewers: Matthias J. Sax <matthias@confluent.io>, John Roesler <john@confluent.io>
fix broken links
rephrase a sentence
update the version number

* 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.

Fixed a small typo on the Processor API page of the Kafka Streams developer guide docs. ("buildeer" changed to "builder")
Reviewers: Bill Bejeck <bbejeck@gmail.com>
* log lock acquistion failures on the state store
* Document required uniqueness of state.dir path
* Move bunch of log calls around task state changes to DEBUG
* More readable log messages during partition assignment

As part of #5425 the streams default override for producer retries was removed. The documentation was not updated to reflect that change.
Reviewers: Matthias J. Sax <mjsax@apache.org>, Sophie Blee-Goldman <sophie@confluent.io>, Bill Bejeck <bbejeck@gmail.com>
Users often use the RocksDBConfigSetter to modify parameters such as cache or block size, which must be set through the BlockBasedTableConfig object. Rather than creating a new object in the config setter, however, users should most likely retrieve a reference to the existing one so as to not lose the other defaults (eg the BloomFilter)
There have been notes from the community that it is not obvious this should be done, nor is it immediately clear how to do so. This PR updates the RocksDBConfigSetter docs to hopefully improve things.
I also piggybacked a few minor cleanups in the docs

This PR intendent to address some typos in https://kafka.apache.org/documentation/streams/developer-guide/processor-api.html page.
Invalid configuration option specified in the example. I've replaced with closest constant TopicConfig.MIN_IN_SYNC_REPLICAS_CONFIG, since LogConfig.MinInSyncReplicasProp() requires Scala stuff
Reference to LogConfig seems to be obsolete, I believe I've moved it to correct line
Apostrophe displayed incorrectly
