> This is needed for testing things like YARN-2646: add an option for the {{MiniYarnCluster}}
to start a {{MicroZookeeperService}}.
> This is just another YARN service to create and track the lifecycle. The {{MicroZookeeperService}}
publishes its binding information for direct takeup by the registry services...this can address
in-VM race conditions.
> The default setting for this service is "off"
