Tuned puppet-zookeeper (on forked repository) to work

on the test server.
 - Tuned the puppet-zookeeper parameters accordingly
 - zookeeper data directory is set to /data0/zookeeper for now
 - Verified on logstream-cd server

TODO:
  This module still will download zookeeper tarball from
  internet while we want to untar from the files delivered
  in OCS.
