docker: move extra services to own file

Description

What does this PR do?

Split docker-compose.yaml file. One compose file only includes the services. For development, it is usually not relevant to have an extra backend and frontend running, since the local development instances for backend and frontend are used.

To run only the extra services, the following command can be executed: docker-compose -f docker-compose-services.yaml up
