Publishing documentation (including release notes) to docs.openstack.org
is not expected from non openstack/* projects.
This patch ensures that release notes are published to docs.opendev.org
together with tempestconf documentation.
Merging of the release notes with tempestconf documentation is
done using symlink created in the docs/source folder.
