Out-of-date work count Docker image in Docker hub

[jmdacruz]

The word count docker image has not been updated (~1 month ago) since #45 was merged (~12 days ago), and hence the quick start guide is broken (unless people build their own image against their own Docker registries, at which point the guide is no longer "quick" :-) ). Besides updating the example image in Docker hub, it would also be useful to tag it, so as to prevent this type of issues in the future.

Thanks for pointing out.

I have built and pushed a new image now. https://cloud.docker.com/u/lyft/repository/registry-1.docker.io/lyft/wordcount-operator-example/tags

Will update the docs to remove usage of latest tag as well.

Sounds good! I just run the example using the tag for the image (3b0347b2cdc1bda817e72b3099dac1c1b1363311) and the cluster is now starting correctly.
