removes job scaler, continued
Builds on https://github.com/kubernetes/kubernetes/pull/61912 (original commit is there for credit/blame)
This keeps all the updates to the scaler building and all the test and reaper cleanup. It just keeps a fake job scaler around for a different command path and the reaper.

Automatically add system critical priority classes at cluster boostrapping
**What this PR does / why we need it**:
We had two PriorityClasses that were hardcoded and special cased in our code base. These two priority classes never existed in API server. Priority admission controller had code to resolve these two names. This PR removes the hardcoded PriorityClasses and adds code to create these PriorityClasses automatically when API server starts.

@smarterclayton
The LocalStorageCapacityIsolation feature added a new resource type
ResourceEphemeralStorage "ephemeral-storage" so that this resource can
be allocated, limited, and consumed as the same way as CPU/memory. All
the features related to resource management (resource request/limit, quota, limitrange) are avaiable for local ephemeral storage.
This local ephemeral storage represents the storage for root file system, which will be consumed by containers' writtable layer and logs. Some volumes such as emptyDir might also consume this storage.

Critical pod priorityClass addition
**What this PR does / why we need it**:
@bsalamat - Apologies for the delay. This PR is to ensure that all pods with priorityClassName `system-node-critical` and `system-cluster-critical` will be critical pods while preserving backwards compatibility.
**Special notes for your reviewer**:
- Moved some constants and other data structures to scheduler/api/types.go where other constants are present.
- An automatic assignment of critical priorities to pods based on critical pod annotation for backwards compatibility including some unit tests.
xref: https://github.com/kubernetes/kubernetes/issues/57471
**Release note**:
```release-note
Critical pods to use priorityClasses.
```

Support for resource quota on extended resources
**Which issue(s) this PR fixes** :
Fixes#46639#57300 for resource quota support
**Special notes for your reviewer**:
One thing to be determined is if it necessary to Explicitly prohibit defining limits for extended resources in quota, like we did for [hugepages](https://github.com/kubernetes/kubernetes/pull/54292#pullrequestreview-74982771), as the resource is not allowed to overcommit.
**Release note**:
```release-note
Support for resource quota on extended resources
