Delete doc/build/html/.root-marker

This file is not needed to be stored in git at all, remove it.

It will be added during publishing process by CI scripts and is only
needed for publishing to docs.openstack.org.

Add doc/build to gitignore file so that no new content will be checked
in.

Add api/autoindex.rst to toctree to fix build.

Add usual build_sphinx stanza to setup.cfg so that building and
publishing in OpenStack CI works. These parameter are crucial.
