Nagios Plugin to monitor Zookeeper

Checks:

1. ruok - checks to see if ZooKeeper reports itself as ok
2. isro - checks to see if ZooKeeper is still writable
3. mode - checks to see if ZooKeeper is in the proper mode (leader/follower) vs standalone
4. avg latency - the average latency reported by ZooKeeper is within the thresholds given. Optional
5. stats - full stats breakdown
6. also reports ZooKeeper version
