Add Dockerfile for running the Django Web Application

[Problem]
Eventually, we'll run the web app on Elastic Beanstalk over Docker.

[Solution]
Create a Dockerfile for running locally. Eventually, there will be a `Dockerfile.prod` that will have production
settings minted in.

[Test]
Tested image with and without Auth0 enabled.
