Move base configuration into `docker-compose.common.yml`

This removes a ton of boilerplate from docker-compose.yml and rather makes us to re-use a significant portion of config.

It does:

• not use extends which is deprecated
• uses YAML anchors to copy existing data
• uses docker-compose.yml overlays that are conveniently joined together
• makes all base configuration be part of docker-compose.common.yml
• makes a services specific configuration be part of docker-compose.services.yml.
