Certbot relies heavily on bash scripts to deploy a development environment and to execute tests. This is fine for Linux systems, including Travis, but problematic for Windows machines.
This PR converts all theses scripts into Python, to make them platform independant.
As a consequence, tox-win.ini is not needed anymore, and tox can be run indifferently on Windows or on Linux using a common tox.ini. AppVeyor is updated accordingly to execute tests for acme, certbot and all dns plugins. Other tests are not executed as they are for Docker, unsupported Apache/Nginx/Postfix plugins (for now) or not relevant for Windows (explicit Linux distribution tests or pylint).
Another PR will be done on certbot website to update how a dev environment can be set up.

Remove the old bootstrap scripts, which have been subsumed into letsencrypt-auto-source/pieces/bootstrappers. They no longer need to be dispatched among manually: everyone can just run letsencrypt-auto --os-packages-only, regardless of OS.
Make the root-level le-auto a symlink to the canonical version. It should thus still work for people running le-auto from a git checkout.
