* 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.
* Restrict Docker SDK for Python to < 7.0.0 in EE.

CI, but in the community.docker CI the problematic runs are on their
own CI node.
