Add `latest` and `earliest` version features that track highest and lowest supported version

[Arnavion]

A few repos like akri have the version feature frozen at a version that happened to be latest version at one time, but then became stale even as the k8s-openapi version was bumped. They may be better served by a latest version feature. And if adding a latest feature, might as well add an earliest feature too.
