Add docker_compose_subprocess_kwargs fixture support

[Toilal]

This allow custom options be passed to underlying subprocess.check_output invocations, like cwd.

@pytest.fixture(scope='session')
def docker_compose_subprocess_kwargs():
return {'cwd': '..'}

Can you justify why do you need this?

[Toilal]

Python sources are lying in a src subdirectory, so pytest runs from this directory. but docker-compose.yml and .env file are in the root directory of the repository, so I need to pass cwd parameter to execute docker-compose (cwd='..').

Ok.

As I don't know when this'll be merged, maybe you can work around it by overwriting docker_compose_file and maybe changing the paths in your compose files?

Thx. I actually use a fork installed with pip right from github, with both submitted pull requests.

May I ask you to resolve the conflicts? 🙏 Thanks!
