Since we weren't autodoc'ing the modules during the docs build, the
module index link was broken.
This generates the module docs (but hides them from the main top-level
table of contents) so they can be accessed via the 'Module Index' link.
Also cleans up some docs issues so that warnerrors=True works during
sphinx-build.
Closes-Bug: #1472642

Replace URLs for workflow documentation to appropriate parts of the
OpenStack Project Infrastructure Manual.
Change-Id: I0fe0dcb62ac8e31d6cda8ad292a9c89c24932e1e
Make repo support 'tox -epep8' as we want this to be the first gating
check.
Don't make any actual code changes, just change setup and add files.
Further work is needed to re-organize the code, but that can be in a
separate patch.
