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

* 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.

As part of #5425 the streams default override for producer retries was removed. The documentation was not updated to reflect that change.

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

Now that we can configure RocksDB to bound the total memory we should include docs describing how, as well as touching on some possible options that should be considered when taking advantage of this feature.
Reviewers: Guozhang Wang <wangguoz@gmail.com>, Jim Galasyn <jim.galasyn@confluent.io>, Bill Bejeck <bbejeck@gmail.com>
The old docs here used a now deprecated method to set the block cache size. In switching over to the new one we would now need to construct a Cache object and therefore also need to close it, so this is a good opportunity to demonstrate the RocksDBConfigSetter#close method that will need to be implemented by users.
