CI is failing with Cannot start service svc1: cgroups: cgroup mountpoint does not exist: unknown, tests locally are failing due to docker: Error response from daemon: manifest for dockerswarm/dind:20.10.3 not found: manifest unknown: manifest unknown., so let's send this to review and hope that CI will be fixed somehow.

LGTM, but please amend your commits for sign-off or we can't accept contributions (git commit amend -s)

But there is a signoff already, dunno what DCO is expecting from me.

Ok, it was expecting the same [real] name as a commit author, pushed with the changed name.

Set up test environment locally and reworked the PR to make it actually work, tests/integration/project_test.py tests pass here (test_up_with_nvidia_runtime is skipped, test_project_up_port_mappings_with_multiple_files fails due to local docker setup).
I've tried to add a test with dependency running top, but looks like project.up() wait for completion even with detached=True, so test hangs.

Ready for review, I guess?

And this time CI on Alpine is green, so I suppose it works 🎉

Rebased on master, CI is green now.
