82009eb5db A optimization for “RegisterCustomFitPredicate” function, avoiding redundancy
In RegisterCustomFitPredicate, when policy.Argument is nil and fitPredicateMap has the policy.Name, it can return the policy.Name directly. Subsequent operations are redundant.

Add pod condition PodScheduled to detect situation when scheduler tried to schedule a Pod, but failed

Set `PodSchedule` condition to `ConditionFalse` in `scheduleOne()` if scheduling failed and to `ConditionTrue` in `/bind` subresource.

Ref #24404

@mml (as it seems to be related to "why pending" effort)

add namespace index for cache

@wojtek-t 

Implement in this approach make the change of lister.go small, but we should replace all `NewInformer()` to `NewIndexInformer()`, even when someone not want to filter by namespace(eg. gc_controller and scheduler). Any suggestion?

Automatic merge from submit-queue

Store node information in NodeInfo

This is significantly improving scheduler throughput.

On 1000-node cluster:
- empty cluster: ~70pods/s
- full cluster: ~45pods/s
Drop in throughput is mostly related to priority functions, which I will be looking into next (I already have some PR #24095, but we need for more things before).

This is roughly ~40% increase.
However, we still need better understanding of predicate function, because in my opinion it should be even faster as it is now. I'm going to look into it next week.

38c7eded99 Prepare for content-type negotiation
Combine the fields that will be used for content transformation
(content-type, codec, and group version) into a single struct in client,
and then pass that struct into the rest client and request. Set the
content-type when sending requests to the server, and accept the content
type as primary.

Will form the foundation for content-negotiation via the client.
