refactor of the DataStore so that we have a ZooKeeper and Git implementation (with the ZooKeeper one still enabled by default)
rollback the change c478e376586b633ca3461843b774a638b002dd59 as at least for me, it seems to cause the fabric to lock up with missing dependencies on startup when running "fabric:create". Hope its working fine for everyone else too & its not just that we've some other timing issue going on!
