Feature: PriorityQueue

[sbueringer]

PriorityQueue is a new feature in controller-runtime. We added a corresponding feature gate to Cluster API to allow testing before priority queue eventually (likely) becomes the only queue implementation in CR.

• PR:
  • CR feature: Feature: Priority Queue controller-runtime#2374
  • CAPI PR: ✨ Add PriorityQueue feature gate #11698
• Feature gate state:
  • Alpha (disabled per default): v1.10
  • Beta (enabled per default): TBD
  • Stable (feature GA): TBD
  • Feature gate removed 1 release later: TBD
