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.
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.

* Use storyboard instead of launchpad since this project uses
storyboard. This fixes the "Report a bug" link.
* Remove unneeded configuration bits for doc building, the
defaults of openstackdocstheme are fine.
