- 'Priority and Fairness has introduced a new feature called _borrowing_ that allows an API priority level
  to borrow a number of seats from other priority level(s). As a cluster operator, you can enable borrowing
  for a certain priority level configuration object via the two newly introduced fields `lendablePercent`, and

- Some apiserver metrics were changed, as follows.
  - `priority_level_seat_count_samples` is replaced with `priority_level_seat_utilization`, which samples every nanosecond rather than every millisecond; the old metric conveyed utilization despite its name.
  - `priority_level_seat_count_watermarks` is removed.

- This PR adds the following metrics for API Priority and Fairness.
  - **apiserver_flowcontrol_priority_level_seat_count_samples**: histograms of seats occupied by executing requests (both regular and final-delay phases included), broken down by priority_level; the observations are taken once per millisecond.

#### Scheduling

* [alpha] This version now supports pod priority and creation of PriorityClasses ([user doc](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/))([design doc](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/scheduling/pod-priority-api.md))

- In the API Priority and Fairness feature, priority levels that are exempt from limitation can now be given a nominal and a lendable concurrency and their dispatching borrows from the concurrency limits of the other priority levels.  For details see https://github.com/kubernetes/enhancements/tree/master/keps/sig-api-machinery/1040-priority-and-fairness#dispatching .

  // The priority value. Various system components use this field to find the

  // The higher the value, the higher the priority.

- Two changes to the `/debug/api_priority_and_fairness/dump_priority_levels` endpoint of API Priority and Fairness: added total number of dispatched, timed-out, rejected and cancelled requests; output now sorted by `PriorityLevelName`.

- Update default API priority-and-fairness config to avoid endpoint/configmaps operations from controller-manager to all match leader-election priority level. ([#106725](https://github.com/kubernetes/kubernetes/pull/106725), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]
