The 2.10 transition has a routing.yml file that points each
individual module from ansible/ansible to a new location. That means
we can put:
into lib/ansible/config/routing.yml in ansible/ansible and have
the result be the end user's playbooks still working with the
old names while providing new names that are less ugly.
This adds a routing file to our collection repo, as well as the
script used to generate the new mapping.
