Release hacking 2.0.0

This gets us onto flake8 3.x along with much newer versions of
pycodestyle, pyflakes and mccabe. The pycodestyle bump is necessary for
f-string support as noted at [1].

Because this version drops support for local plugins, in favour of
flake8's own support for same, we're bumping the major version.
