It allows a counting semaphore to be modeled by a buffered channel:
the number of items in the channel corresponds to the number of active uses,
the capacity of the channel corresponds to the maximum number of simultaneous uses,
sending an item acquires the semaphore, and receiving an item releases
the semaphore.
This is a common idiom for limiting concurrency.

* Add the support to the scheduler for spreading pods of StatefulSets. ([#41708](https://github.com/kubernetes/kubernetes/pull/41708), [@bsalamat](https://github.com/bsalamat))
* Added support to minimize sending verbose node information to scheduler extender by sending only node names and expecting extenders to cache the rest of the node information ([#41119](https://github.com/kubernetes/kubernetes/pull/41119), [@sarat-k](https://github.com/sarat-k))
