Make a few cleanups:
- Remove python 2.7 stanza from setup.py
- Add requires on python >= 3.6 to setup.cfg so that pypi and pip
know about the requirement
- Remove obsolete sections from setup.cfg:
* Wheel is not needed for python 3 only repo
* Some other sections are obsolete
- Update classifiers
- Update requirements, no need for python_version anymore

- bump the openstackdocstheme requirement to 1.20.0, the minimum
recommended version nowadays, and clean the configuration
by removing the options now provided by the theme;
- add the pdf-docs tox environment according the established guidelines;
- remove a useless extra title (for both builders);
- docs tox environment: clean up only the generated html, not the entire
build directory;
- disable the too smart smartquotes option for the latex builder;
- improve the title of the latex document.
