Subject: Uses the kafka image as Zookeeper service...

to reduce image download times and use a supported version.
Initial config is from https://zookeeper.apache.org/doc/r3.4.10/zookeeperAdmin.html#sc_zkMulitServerSetup
and the fixes for stateful set are from https://github.com/solsson/zookeeper-docker
