ZOOKEEPER-3831: add a compatibility test module
ZooKeeper has many external libraries that are dependent on staying
compatible. For example, Apache Curator. This new module will be used to add
compatibility tests for any third party library, tool, etc. that we want to
ensure maintains compatibility. The module is configured with Maven not to
install/deploy so it's only for testing purposes. An initial test using Apache
Curator is added.

Closes #1369 from Randgalt/ZOOKEEPER-3831-add-compatibility-test-module
