Installing amlight/scheduler in kytos-ng env fail: does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found

[Italo Valcy S Brito]

When we try to install amlight/scheduler in the new Kytos-ng environment, the installation fails with the following error:

$ python3 -m pip install -e git+https://github.com/amlight/scheduler#egg=amlight-scheduler
