Drop support for Python 2 and 3.4
Some of our development dependencies, like Sphinx, have already dropped support for Python 2. This makes it harder for this project to update its dependencies. Since Python 2 only has a few more months to live, I think it's fine to drop support now. Python 3.4 has already reached its end-of-life date. Python-RSA now only supports Python 3.5 and newer. Python 3.5 support is intended to last until its end-of-life date of 2019-09-13: https://devguide.python.org/#status-of-python-branches
