- Introduced new apiserver metric `apiserver_flowcontrol_current_inqueue_seats`. This metric is analogous to `apiserver_flowcontrol_current_inqueue_requests`, but tracks the total number of seats, as each request can take more than one seat.

- HPA controller exposes the following metrics from the kube-controller-manager. 
  - `metric_computation_duration_seconds`: The time(seconds) that the HPA controller takes to calculate one metric.
  - `metric_computation_total`: Number of metric computations. ([#116326](https://github.com/kubernetes/kubernetes/pull/116326), [@sanposhiho](https://github.com/sanposhiho)) [SIG Apps, Autoscaling and Instrumentation]
