Stephen Finucane 14872caae1 Stop testing Python 2
It's Ussuri. We can *finally* stop testing Python 2 [1]. Time to party.
We don't attempt any cleanup but simply stop testing with Python 2,
indicate that we only support Python 3 via 'setup.cfg' and remove any
Python 2 only dependencies. Our 'tox.ini' is modified such that
'functional' now runs with 'python3', whatever that may point to, though
the gate will only use a versioned variant (currently
'functional-py36').

This should free up a significant amount of resources from the gate and
let us start using Python 3 idioms in our code. Win-win.

# Most of the whitespace related rules (E12* and E131) are excluded
# because while they are often useful guidelines, strict adherence to
