Shrink size of dev container

[iansmith]

Currently, the dev container is 4.6GB because it includes an ubuntu server and a ton of added packages.

Shrink the size of the devcontainer using multi-stage builds

• https://docs.docker.com/build/building/multi-stage/
• Use alpine for base image

With alpine, we might have to ditch the machinery we currently have that creates a parigot user and then makes all the tools and such owned by the parigot user and group. It's ok if this goes away to get us to a much smaller container size.

There is are already some tags that provide access to an alpine-based container image with golang.
