Remove PEP8 test as it's broken and we have no requirement for it now
ed946f5 
I was seeing the error described here -
PyCQA/pyflakes#367 - when running 'tox'
locally on my own laptop.

That issue indicates that the issue has been fixed upstream, but my
tox environment for some reason has these pins:

    flake8==2.2.4
    pyflakes==0.8.1

I guess hardcoded from within 'tox'?

Anyway, we actually have no requirement to conform to PEP8, so the
simplest thing is just to remove PEP8 testing.

admin: Upgrade flake8 and pylint
b5aea32 
We primarily needed to upgrade pyflakes for Python 3.8 compatibility
(PyCQA/pyflakes#367), but upgrading flake8
also meant pulling in a newer pylint since they have a common
dependency, so here we are.
