Highlights:
* Performance improvements in the ollections
library: algorithmic improvements and
changes to avoid unnecessary allocations.
* Performance improvements in the compiler.
* ASM was upgraded to 7.3.1, allowing the
optimizer to run on JDK 13+.

In the event that `CLASSPATH` does not have an ending ":", the shell
can expand the CLASSPATH globs to be space-separated list of paths/jars,
which is not how the JVM CLI accepts arguments to -cp switch. So
double quote the variable to prevent pattern expansion, and pass the
glob pattern directly to the JVM.

Some shell scripts don't have corresponding batch files in bin\windows.
For improving Windows platform support, This PR adds the following batch files:
- bin\windows\kafka-delete-records.bat
- bin\windows\kafka-log-dirs.bat
Reviewers: Jason Gustafson <jason@confluent.io>
This patch refactors the implementation of the --version option and moves it into the default command options. This has the benefit of automatically including it in the usage output of the command line tools. Several tools had to be manually updated because they did not use the common options.

Removed quotes from LogDir variable generation as there are additional quotes in Line 127.
This caused problems when those batch files are invoked from a path that contains space characters.
Scala 2.12 has better support for newer Java versions and includes additional
compiler warnings that are helpful during development. In addition, Scala 2.11
hasn't been supported by the Scala community for a long time, the soon to be
released Spark 2.4.0 will finally support Scala 2.12 (this was the main reason
preventing many from upgrading to Scala 2.12) and Scala 2.13 is at the RC stage.
It's time to start recommending the Scala 2.12 build as we prepare support for
Scala 2.13 and start thinking about removing support for Scala 2.11.
In the meantime, Jenkins will continue to build all supported Scala versions (including
Scala 2.11) so the PR and trunk jobs will fail if people accidentally use methods
introduced in Scala 2.12.

It seems a tipo was made on a avariable for the log dir with commit 81e789ae3d. Then Windows tries to access by default the /log directory which of cause not exists.
klesta490 Is it ok so? Or was the tilde ~ intentional?
To test:
On Windows with the a fresh downloaded Kafka, adapt the properties:
* dataDir in config/zookeeper.properties with what you want, windows-compatible
* log.dirs in config/server.properties with what you want, windows-compatible
and executes:
bin\windows\zookeeper-server-start.bat config\zookeeper.properties

Removed ignore annotations from the upgrade tests. This PR includes the following changes for updating the upgrade tests:
* Uploaded new versions 0.10.2.2, 0.11.0.3, 1.0.2, 1.1.1, and 2.0.0 (in the associated scala versions) to kafka-packages
* Update versions in version.py, Dockerfile, base.sh
* Added new versions to StreamsUpgradeTest.test_upgrade_downgrade_brokers including version 2.0.0
* Added new versions StreamsUpgradeTest.test_simple_upgrade_downgrade test excluding version 2.0.0
* Version 2.0.0 is excluded from the streams upgrade/downgrade test as StreamsConfig needs an update for the new version, requiring a KIP. Once the community votes the KIP in, a minor follow-up PR can be pushed to add the 2.0.0 version to the upgrade test.
* Fixed minor bug in kafka-run-class.sh for classpath in upgrade/downgrade tests across versions.
* Follow on PRs for 0.10.2x, 0.11.0x, 1.0.x, 1.1.x, and 2.0.x will be pushed soon with the same updates required for the specific version.

- Removed Scala consumers (`SimpleConsumer` and `ZooKeeperConsumerConnector`)
and their tests.
- Removed Scala request/response/message classes.
- Removed any mention of new consumer or new producer in the code
with the exception of MirrorMaker where the new.consumer option was
never deprecated so we have to keep it for now. The non-code
documentation has not been updated either, that will be done
separately.
- Removed a number of tools that only made sense in the context
of the Scala consumers (see upgrade notes).
- Updated some tools that worked with both Scala and Java consumers
so that they only support the latter (see upgrade notes).
- Removed `BaseConsumer` and related classes apart from `BaseRecord`
which is used in `MirrorMakerMessageHandler`. The latter is a pluggable
interface so effectively public API.
- Removed `ZkUtils` methods that were only used by the old consumers.
- Removed `ZkUtils.registerBroker` and `ZKCheckedEphemeral` since
the broker now uses the methods in `KafkaZkClient` and no-one else
should be using that method.
- Updated system tests so that they don't use the Scala consumers except
for multi-version tests.
- Updated LogDirFailureTest so that the consumer offsets topic would
continue to be available after all the failures. This was necessary for it
to work with the Java consumer.
- Some multi-version system tests had not been updated to include
recently released Kafka versions, fixed it.
- Updated findBugs and checkstyle configs not to refer to deleted
classes and packages.

We need to match to the end of the line to make it work with Java 10 as explained in the expanded comment.
Tested manually for all supported versions:
```shell

Different fix for problem addressed by https://github.com/apache/kafka/pull/1953. Should prevent the CLASSPATH environment variable from being prefixed by a single colon before the JVM is invoked in the run-class script, which will then prevent the current working directory from being unintentionally included in the classpath when using the Reflections library.
If the current working directory should still be included in the classpath, it just needs to be explicitly specified either with its fully-qualified pathname or as a single dot (".").

Design:
`zookeeper.connection.retry.timeout.ms` => this determines how long to wait before triggering the shutdown. The default is 60000ms.
Currently the implementation only handles the `handleSessionEstablishmentError` by waiting for the sessionTimeout.

This is important because Bits.reserveMemory calls System.gc() hoping to free native
memory in order to avoid throwing an OutOfMemoryException. This call is currently
a no-op due to -XX:+DisableExplicitGC.
It's worth mentioning that -XX:MaxDirectMemorySize can be used to increase the
amount of native memory available for allocation of direct byte buffers.
