This patch adds a new tox job/command for building the pdf version
of documentation.
tox -epdf-docs
In addition to adjusting the infra requirement for PDF build support,
the following changes are made to build a PDF doc.
- Inline sample config file is skipped for PDF doc
to avoid an LaTeX error "TeX capacity exceeded".
- Download link of sample config and policy files are disabled
for PDF doc as relative links do not make sense.
- "Search" and "genindex" page is only enabled for HTML doc
as they work only for HTML doc.
