Make the prometheus plugin listen on 127.0.0.1 (localhost) by default
instead of open to the world. This closes a privacy breach in the
default configuration.
Poetry will automatically manage virtualenvs for our project, so we
can rely on `poetry install` and `poetry run` in the main environment
to keep the nested env up-to-date and enter it for testing.
In a clean machine a new user will endup with the following exception

The old skipIf annotation doesn't seem to work correctly:
```
PytestUnknownMarkWarning: Unknown pytest.mark.skipIf - is this a typo?

for details, see https://docs.pytest.org/en/stable/mark.html
@pytest.mark.skipIf(True, "Test autopilot is hanging on DNS request")
```
This commit try to solve the following exception with an additional sanity check:
```
