This configuration file is intentionally distinct from `pytest.ini`.

So for instance, people working on a project with functional tests
against a Heptapod instance can set the URL of their Heptapod instance
in `heptapod-tests.yml` and hg ignore that file.

The special case of the boolean action options (`store_true`) led to
some complications, because the only way to detect that it's not
passed on the CLI is that the value is the other alternative.
