Auto push new image to Docker Hub on succesful build

[pickles-bread-and-butter]

Overview:

Currently our images on docker hub are horribly out of date. We should be building a docker image automatically when we have a succesful new build on master. This should be a relatively easy to integrate change, https://docs.docker.com/docker-hub/builds/, docker allows you to build images when linked repos are updated and adds to docker builds.

ToDo:

• Investigate most efficient way to automatically build docker image and push to docker hub
• Integrate with CI platform or docker hub to automatically make build.

Hey @isaak-willett, I think this is a great idea. Docker hub builds even supports automated tests. If you go with docker hub, we could add test cases that prevent the new images from being pushed to the docker hub repository unless the tests pass. Obviously I don't have access to login and configure it, but let me know if there is anyway I can help!
