rm Cloud variant; mv CloudImages Cloud
We need to stop building repos and install media for the *Cloud* variant
because the only consumers of those repos/install media is the cloud
base images that could easily be built with the Everything repo/install
media. This commit removes the cloud variant (as it was previously
known) and then renames the CloudImages variant to 'Cloud'.
Summary:
- Cloud now becomes an empty variant (no repos, no install media)
- CloudImages variant goes away
- Cloud image builds use Everything repo/install media
- Atomic image builds use Everything install tree
