Moncic-CI could snapshot the image before running image maintenance on it, and if maintenance succeed, swap the upgraded snapshot with the old one, and remove the old one.

The swapping would not be atomic, but it would still greatly reduce the time in which an image being upgraded is in an inconsistent inbetween state, and it would keep the previous version in case the upgrade fails.

It would also allow running faster upgrades using --suppress-sync=yes
