https://cdimage.debian.org/cdimage/openstack/testing/ not updated

[Renzo Davoli <renzo@cs.unibo.it>]

The images at:
https://cdimage.debian.org/cdimage/openstack/testing/
should provide updated cloud images of the Debian/testing.

Unfortunately the images have not been updated since July 1st 2019
and the checksums are just empty files (and the signature of checksums are
signatures of empty files).

Can you please fix the service? I would like to use those images for 
virtualsquare (virtualsquare.org) tutorials.

thank you in advance.
