Use external Zookeeper in Local mode

Browse Source 
By default Storm uses the in-process ZooKeeper when the local mode
is chosen.

The in-process ZooKeeper doesn't handle the trim of ZooKeeper
Transactional logs & snapshots.

There is a constructor which enables the possibility to use an
external ZooKeeper when the local mode is used. [1][2]
