master <- Docker branch

[ekansa]

brief description of changes

I added a section about using Docker to install Arches, with sections on using Docker to test Arches and another about use of Docker for production deployments of Arches. I referenced three repos where Docker is used for development and testing of Arches as well as my repo that uses Docker for production deployment of Arches.
