I updated the readme, added a configmap, and updated the statefulset definition to add the prometheus sidecar.

Note: I installed kafka on stage using these exact files so I believe they work as we would expect them to.

The readiness fails and the containers will never start if they use the readiness probe used by charts since jmx is using port 5000: https://github.com/kubernetes/charts/blob/master/incubator/kafka/templates/statefulset.yaml#L61

This one works: https://github.com/Yolean/kubernetes-kafka/blob/master/kafka/50kafka.yml#L63

Ahh okay, it's good that we pulled the change from the upstream that this chart is meant to be based on. It's more defensible if we try to merge these changes into the upstream chart.

Thanks

Note that this is basically a helmification of the changes at: Yolean/kubernetes-kafka@5a2b8c7

Also changes the readiness probe to match the new one upstream
