Subject: [PATCH] Reorder Dockerfile to improve build times

Although the original Dockerfile was quite simple and straightforward,
it wasn't necessarily fast for doing repeated builds (local testing).

By putting things first which rarely change (pip install of base
requirements, for example), we can take advantage of docker caching to
skip redundant build steps.
