History
Carlos Goncalves 1f9619cdb5 Download latest CentOS cloud image 
DIB was retrieving the oldest cloud image file which, presently, means
retrieving CentOS 8.1 instead of CentOS 8.2. Even though DIB runs a
system update and so catches up to latest, this takes bandwidth, time
and final image space (8.1 + system update = 765M qcow2, vs 8.2 + system
update = 518M qcow2).

This patch fixes that by taking the first image name in a descending
order list.
