Just

[jennydaman]

This PR adds a justfile, an 80-line replacement to the over 1,400 lines of bash scripts we use for development.

$ just --list --unsorted
Available recipes:
    dev                     # Start the ChRIS backend in development mode, and attach to the live-reloading server.
    start                   # Start the ChRIS backend in development mode.
    up                      # Start services (without running database migrations).
    attach                  # Attach to the chris container.
    shell                   # Open a Python shell.

Advantages

• maintainability: declarative and >10x fewer SLoC
• performance: make.sh has a lot of overhead, just is simpler and faster
• sane defaults: run just instead of docker swarm leave --force && docker swarm init --advertise-addr 127.0.0.1 && ./unmake.sh && sudo rm -fr CHRIS_REMOTE_FS && rm -fr CHRIS_REMOTE_FS && ./make.sh -U -I -i
• clarity and convenience: you can easily run subcommands and tests like just test pacsfiles instead of one-letter flag arguments
• switched from using docker swarm to just docker
• switched from using swift storage to filesystem storage
