Clark Boylan c25e91f496 Generate list of 404s for docs.o.o
This generates a list of 404s by count for docs.openstack.org.
This simple list will be hosted at https://files.openstack.org/docs-404s
and can be used by projects to update their rewrite rules to properly
redirect old urls to current urls.
