Bonfire needs to declare its dependency on setuptools

[awood]

After upgrading from F38 to F39, I bumped into the following

Traceback (most recent call last):

    import bonfire.config as conf

    from pkg_resources import resource_filename                                                           
ModuleNotFoundError: No module named 'pkg_resources'   

I did a pip install -U setuptools which fixed the problem, but I think bonfire needs to declare setuptools as a runtime dependency under 'projectrather that just abuild-system` dependency.
