PDF Documentation Build tox target

This patch adds a `pdf-docs` tox target that will build
PDF versions of our docs. As per the Train community goal:

  https://governance.openstack.org/tc/goals/selected/train/pdf-doc-generation.html

Add sphinxcontrib-svg2pdfconverter to doc/requirements.txt
to convert our SVGs.
