- part of KIP-572
- deprecates producer config `retries` (still in use)
- deprecates admin config `retries` (still in use)
- deprecates Kafka Streams config `retries` (will be ignored)
- adds new Kafka Streams config `task.timeout.ms` (follow up PRs will leverage this new config)

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).

This change updates ConsoleProducer, ConsumerPerformance, VerifiableProducer, and VerifiableConsumer classes to add and prefer the --bootstrap-server flag for defining the connection point of the Kafka cluster. This change is part of KIP-499: https://cwiki.apache.org/confluence/display/KAFKA/KIP-499+-+Unify+connection+name+flag+for+command+line+tool.

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>
Document the upgrade path for the consumer and for Streams (note that they differ significantly).
Needs to be cherry-picked to 2.4
