Fix 'Schedulercache is corrupted' error
Fixes#50916
If an Assume()ed pod is Add()ed with a different nodeName, the podStates view of the pod is not corrected to reflect the actual nodeName. On the next Update(), the scheduler observes the mismatch and process exits.
```release-note
Fixed 'Schedulercache is corrupted' error in kube-scheduler
```
Refactor the kube-scheduler configuration API, command setup, and server
setup according to the guidelines established in #32215 and using the
kube-proxy refactor (#34727) as a model of a well factored component
adhering to said guidelines.
* Config API: clarify meaning and use of algorithm source by replacing
modality derived from bools and string emptiness checks with an explicit
AlgorithmSource type hierarchy.
* Config API: consolidate client connection config with common structs.
* Config API: split and simplify healthz/metrics server configuration.
* Config API: clarify leader election configuration.
* Config API: improve defaulting.
* CLI: deprecate all flags except `--config`.
* CLI: port all flags to new config API.
* CLI: refactor to match kube-proxy Cobra command style.
* Server: refactor away configurator.go to clarify application wiring.
* Server: refactor to more clearly separate wiring/setup from running.
Fixes#52428.

@jiayingz Sorry, there is something wrong with my branch in #51895. And I think the existing comments in the PR might be too long for others to view. So I closed it and opened the new one, as we have basically reach an agreement on the implement :)
I have covered the functionality and unit test part here, and would set about the e2e part ASAP

Optimize Repeated registration of AlgorithmProvider when ApplyFeatureGates
**What this PR does / why we need it**:
modified ApplyFeatureGates() just add/del features, cancel the register of all AlgorithmProvider.
there is Repeated registration of all AlgorithmProvider when ApplyFeatureGates() runs;
AlgorithmProvider have already registered when package defaults loaded;
I think ApplyFeatureGates() is just add/del features, it needn't register all AlgorithmProvider again

Besides remove the unused port from map will save the memory.

pkg/api: extract Scheme/Registry/Codecs into pkg/api/legacyscheme
This serves as
- a preparation for the pkg/api->pkg/apis/core move
- and makes the dependency to the scheme explicit when vizualizing
left depenncies.
The later helps with our our efforts to split up the monolithic repo
into self-contained sub-repos, e.g. for kubectl, controller-manager
and kube-apiserver in the future.
