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 
the other thing I was thinking about is the case of multiple children.  Can you add the following to this test

 * reinit /very/long/path2
 * assert /very/long/path exist
 * assert /very/long/path2 exist

Just want to make sure that /very/long/path is not deleted when creating a sibling node.
