Several changes to deprecate the MidoNet's zookeeper module. Deric's
Zookeeper:
https://github.com/deric/puppet-zookeeper
Is well mantained and it has much more functionality. So the commit
replaces the dependencies and sets some changes to adapt to the new
module.
I have kept the ::midonet::zookeeper manifest to maintain backwards
compatiblity with tools that use MidoNet 2015.01 version.
So the ::midonet::zookeeper manifest is just a gangway to the actual's
deric one now.
