Ensure application adheres to the Twelve Factor App methodology

[kylejb]

One popular methodology that can help you focus on the characteristics that matter most when creating cloud-ready web apps is the Twelve-Factor App philosophy. Originally written to help developers and operations teams understand the core qualities shared by web services designed to run in the cloud, the principles apply very well to software that will live in a clustered environment like Kubernetes. While monolithic applications can benefit from following these recommendations, microservices architectures designed around these principles work particularly well.
