Refactor `reconcileAutoscaler` method in hpa **What this PR does / why we need it**: There have been a couple of recent bugs in the "normalizing" part of the `reconcileAutoscaler` method. This part of the code base is responsible for, among other things, taking the suggested desired replicas based on the metrics, ensuring it conforms to certain conditions, and updating it if it does not. Isolate the part that converts the desired replicas based on a given set of rules into its own function. We are refactoring this part of the code base to make the logic simpler and to make it easier to write unit tests. **Which issue this PR fixes**: Fixes #53728 **Release note**: ```release-note NONE ```
