Two Week process enhancements
Today there is no good way to follow just the stable two week Atomic Host, as the ostree is updated every stable updates push
The scope of the changes is to make minor adjustments to the process not a wholesale rewrite
The limit of the changes on the ostree side of the process is to keep track of the commits used in the stable two week push, we would then tag that commit with a stable ref at compose push live time the ref would be something like fedora-atomic/24/x86_64/stable-docker-host and would be signed we would still pull from the repo created by bodhi.
We need to ensure that the images build are set to follow the ref we tag as stable, it should be a matter of making a ostree call in the kickstart to change the ref.
We need to make sure that the ref followed is the stable ref on the installed system
