Download latest CentOS cloud image

Browse Source 
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.
