Modifying configuration options (ignored modules, extra repositories,
hooks) for autohelp requires an update of the doc-tools repository,
which doesn't make much sense since the goal is to update the manuals

This patch imports the configuration items, and autohelp.py has been
patched to make use of them in https://review.openstack.org/265274
