Switch to using pbr's autodoc capability

Once we use the pbr based build to generate files, we prune
the indexes to remove references to code we would like to
hide like the common modules and private modules in conf.py.
We reuse the same excluded_patterns variable that is already
used in Sphinx and filter these modules from autoindex.rst
