Why are we deleting Dockerfile?

@thepsalmist ☝🏽 ... why are we deleting Dockerfile and keeping Dockerfile.dev?

We have respective Dockerfiles in contrib/. This was cleanup. I think we need Dockefle.dev

It's a bit confusing @thepsalmist ... I'm looking at the docker-compose-dev.yml file and it's pointing to

      build:
        context: contrib/postgres
        dockerfile: Dockerfile

Not sure what is what. Why do we need a separate dev? Why not switch to multi-stage if we do indeed need a different dev?
