Kubernetes Submit Queue b932c82739 Merge pull request #39803 from jayunit100/sched_cleanup_config_1 
Automatic merge from submit-queue (batch tested with PRs 39803, 39698, 39537, 39478)

Use controller interface for everything in config factory

**What this PR does / why we need it**:

We want to replace controller structs with interfaces 
- per the TODO in `ControllerInterface`
- Specifically this will make the decoupling from Config and reuse of the scheduler's subcomponents cleaner.

Justin Santa Barbara 511b2ecaa8 Avoid hard-coding list of Node Conditions 
We assume that if a Condition isn't well-known, that it blocks
scheduling of pods, and that the "unhealthy" value is api.ConditionTrue

Kubernetes Submit Queue b0a4216182 Merge pull request #33763 from jayunit100/sched-checkservice-predicateCache 
Automatic merge from submit-queue

Predicate cacheing and cleanup

Fix to #31795 

First pass @ cleanup and caching of the CheckServiceAffinity function.  

The cleanup IMO is necessary because the logic around the pod listing and the use of the "implicit selector" (which is reverse engineered to enable the homogenous pod groups).

Should still pass the E2Es.

Exit scheduler retry loop correctly 
The error was being eaten and shadowed, which means we would never exit
this loop. This might lead to a goroutine in the scheduler being used
forever without exiting at maximum backoff.

Switched to use the real client to make later refactors easier.

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.

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.
