Switch to openstackdocstheme 2.2.1 and reno 3.1.0 versions. Using
these versions will allow especially:
* Linking from HTML to PDF document
* Allow parallel building of documents
* Fix some rendering problems
Update Sphinx version as well.
Set openstackdocs_pdf_link to link to PDF file. Note that
the link to the published document only works on docs.openstack.org
where the PDF file is placed in the top-level html directory. The
site-preview places the PDF in a pdf directory.
Disable openstackdocs_auto_name to use 'project' variable as name.
Change pygments_style to 'native' since old theme version always used
'native' and the theme now respects the setting and using 'sphinx' can
lead to some strange rendering.
Remove docs requirements from lower-constraints, they are not needed
during install or test but only for docs building.
openstackdocstheme renames some variables, so follow the renames
before the next release removes them. A couple of variables are also
not needed anymore, remove them.

README.rst and doc/source/index.rst are modified a bit
to fit both HTML and PDF docs.

Story: 2006099
Task: 35138
Start publishing docs with using the proper template.
For this, add also a doc/requirements.txt file and move docs
requirements there. Update tox.ini for this and use the modern way to
invoke sphinx-build for building.
Remove obsolete sectoins from setup.cfg.
Update the conf.py files and remove unused lines
with newer openstackdocstheme - and require newer theme.
Fix indents in CONTRIBUTING.rst so that the formatting works nicely.
Also, use lower-constraints template instead of individual jobs.
