Addressing 1:1 Dependency Between MCO and Butane

[yasminvalim]

This issue intends to investigate and discuss the 1:1 dependency between MCO and Butane. The objective is to understand this dependency and explore the possibility of untangling it to ensure a smoother release process.

However, if there is no immediate solution, we will take a few actions to prevent unplanned releases:

• Incorporate GA release dates into coreos-packages Google agenda.
• Set reminders in Slack as the GA release dates approach.

There is a 1:1 match between the openshift variants and openshift releases to let users use a spec version matching their openshift release at all times, without having to think about compatibility. A config written with the 4.15.0 spec should work on a 4.15.0 (and later) cluster, etc.
