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 
Whats the behavior of this code with a root like `/test/fluo1`?  Will it delete `/test` or `/test/fluo1`?  Should we have an IT for this reinit case?  Maybe could be part of #300
