Integration tests: split up Docker setup, move docker_compose tests into own group (#718)

* Rename setup role.

* Create new CI group 6, and move docker_compose v1 tests into there.

* Split up Docker setup in integration tests.

* Change setup_docker_compose_v1 to install its own Docker SDK for Python.

* Docker SDK for Python not needed to set up registry or query host info.
