Calyptos: Zookeeper server id not being set

[dmccue]

/var/lib/zookeeper/data/myid is not being populated with correct server ID

Related to #75

The server identifier in /etc/zookeeper/zoo.cfg should be written to each server's /var/lib/zookeeper/data/myid
e.g.
server.2=10.105.10.70:2888:3888
equals
echo 2 > 10.105.10.70:/var/lib/zookeeper/data/myid

This needs to be done within the midokura-cookbook
