Set dachs:latest to auto-start postgres/dachs

[chbrandt]

Currently, during initialization, dachs just prints a help message and keeps waiting for users to start/run the services on their own (

docker-dachs/dockerfiles/dachs/Dockerfile

Line 91 in 40cc387

CMD ["--rcfile", "/help.sh"]

).

Suce behavior is welcome when a simple docker run is used, but we can do better -- ie, start the services automatically -- when using docker-compose (through command).

We can specify a different entrypoint from the dachs/Dockerfile#L91 in docker-compose.yml#L14.

This way docker-compose starts dachs automagically, but running the image alone makes possible to validate & ingest the data.

Good point @kidpixo . Do you happen to have a couple of cycles to do it? 🤞
