Remove most Python 2 mentions from docs. Exclusions:

- `docs/tutorials/wiki/*` was written for Python 2 and supposedly won't run on Python 3.
- `docs/api/compat.rst` because it drops some stuff and moves other bits into `pyramid.util` and should be part of another PR.
- Ignored a couple of times where `env27` and `Python 2.` appear in command output, but they are inconsequential.
