KNOX-2121 - Zookeeper - Reduce amount of resources required to run tests (#190)
Our Zookeeper tests don't require 3 instances
for them to run. We can instead use 1 instance
and run the tests with fewer resources.
The timeout for cluster starting up is determined
by hostname lookup speed and can't easily be changed.

> Currently, most of the Zookeeper tests spin up 3 test instances using the curator TestingCluster framework. Under heavily loaded test machines or running a bunch of tests in parallel, the nodes don't start quick enough. Curator sets this timeout value based on hostname lookup time.
> Instead of spinning up multiple Zookeeper instances, we can test with just a single instance. There aren't any tests that rely on multiple ZK instances to be running.
