Closes #294 - Fluo now uses a chroot suffix in its Zookeeper connection ...

Removed old ZK root prop & added Accumulo ZK connect prop.

Pull request for #294 
would be nice to try a few different configs here... like `localhost`, `localhost/`, `localhost:9999/`, `localhost:9999`, `localhost/ ` .... maybe make the test do `foreach(String zk : new String[]{"localhost", "localhost/", etc}`
