Kubernetes primitives that our Cluster Federation control plane
supports, expanding the number of approaches taken to multi-cluster
management (beyond our initial Federation approach), and preparing
to release Federation for general availability ('GA').

- Graduated the `ReadWriteOncePod` feature gate to `GA`. ([#121077](https://github.com/kubernetes/kubernetes/pull/121077), [@chrishenzie](https://github.com/chrishenzie))
- Graduated the following kubelet resource metrics to **general availability**:
  - `container_cpu_usage_seconds_total`
  - `container_memory_working_set_bytes`
  - `container_start_time_seconds`
  - `node_cpu_usage_seconds_total`
  - `node_memory_working_set_bytes`

- Kube-apiserver: redirects from backend API servers are no longer followed when checking availability with requests to `/apis/$group/$version` ([#112772](https://github.com/kubernetes/kubernetes/pull/112772), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

- Fixed CSI migration of Azure Disk in-tree StorageClasses with topology requirements in Azure regions that do not have availability zones. ([#109154](https://github.com/kubernetes/kubernetes/pull/109154), [@jsafrane](https://github.com/jsafrane))
