bring the development docker image down from 3.6GB -> 2.4GB
add a production docker image that weighs in at 1.2GB, which should speed
up end-to-end tests
template-ize web Dockerfiles so that common stuff stays consistent, volume
dirs are set up properly, etc.
test plan:
1. docker-based builds should pass
2. docker image should be usable (docker-compose up, etc)
