Full stack docker compose file for local dev

[mtfoley]

A docker compose file would be useful for contributors although it wouldn't be the full picture (since the database is really a database from the API which we have some steps for setting up: https://github.com/open-sauced/api#%EF%B8%8F-setting-up-a-postgresql-database-locally).

It could be very cool to have a docker compose that captures more of the stack to give a full local development experience.
