KAFKA-1888 [WIP]: rolling upgrade test
@ewencp @gwenshap
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

> To help test upgrades and compatibility between versions, it will be cool to
> add a rolling-upgrade test to system tests:
> Given two versions (just a path to the jars?), check that you can do a
> rolling upgrade of the brokers from one version to another (using clients
> from the old version) without losing data.
