- 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)

Brokers currently return NOT_LEADER_FOR_PARTITION to producers and REPLICA_NOT_AVAILABLE to consumers if a replica is not available on the broker during reassignments. Non-Java clients treat REPLICA_NOT_AVAILABLE as a non-retriable exception, Java consumers handle this error by explicitly matching the error code even though it is not an InvalidMetadataException. This PR renames NOT_LEADER_FOR_PARTITION to NOT_LEADER_OR_FOLLOWER and uses the same error for producers and consumers. This is compatible with both Java and non-Java clients since all clients handle this error code (6) as retriable exception. The PR also makes ReplicaNotAvailableException a subclass of InvalidMetadataException.
- ALTER_REPLICA_LOG_DIRS continues to return REPLICA_NOT_AVAILABLE. Retained this for compatibility since this request never returned NOT_LEADER_FOR_PARTITION earlier.
- MetadataRequest version 0 also returns REPLICA_NOT_AVAILABLE as topic-level error code for compatibility. Newer versions filter these out and return Errors.NONE, so didn't change this.
- Partition responses in MetadataRequest return REPLICA_NOT_AVAILABLE to indicate that one of the replicas is not available. Did not change this since NOT_LEADER_FOR_PARTITION is not suitable in this case.

This applies to the producer, consumer, admin client, connect worker
and inter broker communication.
`ClientDnsLookup.DEFAULT` has been deprecated and a warning
will be logged if it's explicitly set in a client config.

1. Enables `TLSv1.3` by default with Java 11 or newer.
2. Add unit tests that cover the various TLSv1.2 and TLSv1.3 combinations.
3. Extend `benchmark_test.py` and `replication_test.py` to run with 'TLSv1.2'
or 'TLSv1.3'.

Closes#8139 from rondagostino/KAFKA-9575
Removes references to the old scala Acl classes from kafka.security.auth (Acl, Operation, ResourceType, Resource etc.) and replaces these with the Java API. Only the old SimpleAclAuthorizer, AuthorizerWrapper used to wrap legacy authorizer instances and tests using SimpleAclAuthorizer continue to use the old API. Deprecates the old scala API.

* 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.

Splits the existing StickyAssignor logic into an AbstractStickyAssignor class, which is extended by the existing (eager) StickyAssignor and by the new CooperativeStickyAssignor which supports incremental cooperative rebalancing.
There is no actual change to the logic -- most methods from StickyAssignor were moved to AbstractStickyAssignor to be shared with CooperativeStickyAssignor, and the abstract MemberData memberData(Subscription) method converts the Subscription to the embedded list of owned partitions for each assignor.
The "generation" logic is left in, however this is always Optional.empty() for the CooperativeStickyAssignor as onPartitionsLost should always be called when a generation is missed.

Api exception types usually have a single argument constructor which accepts the exception message. However, some types actually use this constructor to initialize a field. This inconsistency has led to some cases where exception messages were being incorrectly passed to these constructors and interpreted incorrectly. For example, this leads to confusing messages like the following in the log when we hit a GROUP_MAX_SIZE_REACHED error:
```
Attempt to join group failed due to fatal error: Consumer group The consumer group has reached its max size. already has the configured ...
```
This patch fixes the problem by changing these constructors so that the exception message is provided consistently. This affected `GroupAuthorizationException`, `TopicAuthorizationException`, and `GroupMaxSizeReachedException`.

This commit makes three changes:
- Adds a constructor for NewTopic(String, Optional<Integer>, Optional<Short>)
which allows users to specify Optional.empty() for numPartitions or
replicationFactor in order to use the broker default.
- Changes AdminManager to accept -1 as valid options for replication
factor and numPartitions (resolving to broker defaults).
- Makes --partitions and --replication-factor optional arguments when creating
topics using kafka-topics.sh.
- Adds a dependency on scalaJava8Compat library to make it simpler to
convert Scala Option to Java Optional
