For now, Kafka system tests use python2 which is outdated and not supported.
This PR upgrades python to the third version.

To avoid transient system test failures, tolerate a small amount of data loss due to truncation in upgrade system tests using older message format prior to KIP-101, where data loss was possible.

This commit creates an EndToEndTest base class which relies on the verifiable consumer. This will ultimately replace ProduceConsumeValidateTest which depends on the console consumer. The advantage is that the verifiable consumer exposes more information to use for validation. It also allows for a nicer shutdown pattern. Rather than relying on the console consumer idle timeout, which requires a minimum wait time, we can halt consumption after we have reached the last acked offsets. This should be more reliable and faster. The downside is that the verifiable consumer only works with the new consumer, so we cannot yet convert the upgrade tests. This commit converts only the replication tests and a flaky security test to use EndToEndTest.
The bump from 0.11.1.0-SNAPSHOT to 1.0.0-SNAPSHOT broke a couple
of system tests:
* TestVerifiableProducer.test_simple_run
* KafkaVersionTest.test_multi_version

Closes#3587 from ijuma/fix-_kafka_jar_versions
## Fixes race condition in TestVerifiableProducer sanity test:
The test starts a producer, waits for at least 5 acks, and then
logs in to the worker to grep for the producer process to figure
out what version it is running.
The problem was that the producer was set up to produce 1000 messages
at a rate of 1000 msgs/s and then exit. This means it will have a
typical runtime slightly above 1 second.
Logging in to the vagrant instance might take longer than that thus
resulting in the process grep to fail, failing the test.
This commit doesn't really fix the issue - a proper fix would be to tell
the producer to stick around until explicitly killed - but it increases
the chances of the test passing, at the expense of a slightly longer
runtime.

Added CompressionTest that tests 4 producers, each using a different compression type and one not using compression.
Enabled VerifiableProducer to run producers with different compression types (passed in the constructor). This includes enabling each producer to output unique values, so that the verification process in ProduceConsumeValidateTest is correct (counts acks from all producers).
Also a fix for console consumer to raise an exception if it sees the incorrect consumer output (before we swallowed an exception, so was hard to debug the issue).

This needs some refactoring to avoid the duplicated code between replication test and upgrade test, but in shape for initial feedback.
I'm interested in feedback on the added `KafkaConfig` class and `kafka_props` file. This addition makes it:
- easier to attach different configs to different nodes (e.g. during broker upgrade process)
- easier to reason about the configuration of a particular node
Notes:
- in the default values in the KafkaConfig class, I removed many properties which were in kafka.properties before. This is because most of those properties were set to what is already the default value.
- when running non-trunk VerifiableProducer, I append the trunk tools jar to the classpath, and run it with the non-trunk kafka-run-class.sh script
