Official Docker Image

[Елисей Занько]

Hi folks,

    I've submitted this PR
<https://github.com/docker-library/official-images/pull/1765> to Docker
Official Images <https://github.com/docker-library/official-images>. It's
based on 31z4/zookeeper <https://hub.docker.com/r/31z4/zookeeper/>.
    Would be great to get some feedback! Or maybe somebody from the team
would like to collaborate on the image.

Thanks!
