Integrate Quay.io to the Dockerfile Build and Test artifacts

[karlmutch]

As an integrator
I want to be able to trigger image builds on commits to github
In order that Build and Test images can be generated and stored in a publicly accessible repository for use by CI pipelines on an platform cloud or otherwise

Quay.io offers a service where github repositories can be monitored for Dockerfile commits and then will trigger a build of associated images automatically without needing user infrastructure, or secrets management and opaque Travis workflows.

Downstream in the CI pipeline the generated images can then be observed by tooling such as keel to actually respond to the appearance of the images and instructed to run the same automatically to perform builds. This approach can also be used on an individuals workstation without needing external coupling. There is an example of doing this inside the go runner repository.

Producing documentation describing the use of the Dockerfiles and the Quay.io repository creation is needed.

Depends on #364
