The key point is that a magnum resource is created and viewable with the
command line, but not in the Horizon dashboard
Test -proposed:
---------------
sudo apt install python3-magnumclient=4.4.0-0ubuntu1.1
Restart Horizon dashboard to restart the wsgi and reload the magnumclient
sudo systemctl restart apache2
