add an example for deploying in kubernetes with the strimzi operator

[dcharbonnier]

This is a minimal example, the deployment should be tuned.

  name: burrow-config

  burrow.toml: |

    servers=[ "{{cluster}}-cluster-zookeeper-client.{{namespace}}.svc.cluster.local:2181" ]

    tls="zookeeper"

    [tls.zookeeper]
    keyfile="/burrow-ca-key/ca.key"
    certfile="/burrow-ca-crt/ca.crt"
    cafile="/burrow-ca-crt/ca.crt"

    [client-profile.default]

Hi @dcharbonnier,

Thank you for sharing this with us, I'd like to ask you about the used image for Burrow. Would you please share it?

[dcharbonnier]

I did a clone of burrow on our private git and added ci to build and push an image on our private registry using the included dockerfile
