Support using Docker for development

[iqqmuT]

This is a breaking change for production!

Docker Compose must be run in this way in production:

docker-compose -f docker-compose.yml -f docker-compose.production.yml up

Docker compose files:

File	Purpose
docker-compose.yml	Base file
docker-compose.override.yml	Override file to use in development, used by default when running docker-compose up
docker-compose.production.yml	Override file to use in production, not using docker-compose.override.yml
