docker-compose conventions

Service naming convention

# Due to lack of "expressivity" in Compose, we define our own couple of service "pseudo-types":
#
#   - image-only services (name: *-image)
#     The only goal of these is to build images. No other services build images.
#     These have entrypoint overridden to exit immediately.
