WIP: docker compose file to quickly bring up the development environment

Instead of having to install proper versions of software of local machine, we will pull small alpine images for all the services we need, dividing huge and time consuming task of preparing gitlab environment to many small tasks.

Aiming to close #135 and #131

  • docker-compose should start all necessary services
  • add this development method to documentation
  • make sure that postgres data survives between docker container restarts
  • squash and rebase before merge
