Set up a -1 release convenience tag

[castrojo]

Since the OCI feature from Fedora we need to go stable has been punted to F40 we should set up a convenience tag for the latest release -1 so we can get 2 major upgrades under our belt. Here's the spec from a while back.

For the main repo images this is done in this PR #301

From @EyeCantCU

39 won't get pushed to that until it is marked as stable. When that happens, we set the flag for latest and stable releases to false for 38 but keep gts true and that will be the release that stays behind.

So when f39 hits stable, we should see gts pop up in our tags for f38.

After looking at the changes, I think we need to implement it for all the other repo's where we want to use this strategy the same way. It will not flow down automaticly.

I can get that setup sometime today :)

Tried to make a list with all the PR's implemented this for easier tracking. I hope i've got them all.
