failureDomains are only used for PreferredDuringScheduling pod
anti-affinity, which is ignored by PodAffinityChecker.
This unnecessary requirement was making it hard to move
PodAffinityChecker to GeneralPredicates because that would require
passing --failure-domains to both kubelet and kube-controller-manager.

[scheduler] Use V(10) for anything which may be O(N*P) logging
Fixes#37014
This PR makes sure that logging statements which are capable of being called on a perNode / perPod basis (i.e. non essential ones that will just clog up logs at large scale) are at V(10) level.
I dreamt of a levenstein filter that built a weak map of word frequencies and alerted once log throughput increased w/o varying information content.... but then I woke up and realized this is probably all we really need for now :)
- Prevents kubelet from overwriting capacity during sync.
- Handles opaque integer resources in the scheduler.
- Adds scheduler predicate tests for opaque resources.
- Validates opaque int resources:
- Ensures supplied opaque int quantities in node capacity,
node allocatable, pod request and pod limit are integers.
- Adds tests for new validation logic (node update and pod spec).
- Added e2e tests for opaque integer resources.

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.

Comments addressed, Make emptyMetadataProducer a func to avoid casting,
FakeSvcLister: remove error return for len(svc)=0. New test for
predicatePrecomp to make method semantics explictly enforced when meta
is missing. Precompute wrapper.

Add kubelet awareness to taint tolerant match caculator.
Add kubelet awareness to taint tolerant match caculator.
Ref: #25320
This is required by `TaintEffectNoScheduleNoAdmit` & `TaintEffectNoScheduleNoAdmitNoExecute `, so that node will know if it should expect the taint&tolerant

simplify RC and SVC listers
Make the RC and SVC listers use the common list functions that more closely match client APIs, are consistent with other listers, and avoid unnecessary copies.

Fix minor nits in test cases
Found a group of nits when doing #30844, fixed them in a this PR since 30844 requires a long time to review.

Initial support for pod eviction based on disk
This PR adds the following:
1. node reports disk pressure condition based on configured thresholds
1. scheduler does not place pods on nodes reporting disk pressure
1. kubelet will not admit any pod when it reports disk pressure
1. kubelet ranks pods for eviction when low on disk
1. kubelet evicts greediest pod
Follow-on PRs will need to handle:
1. integrate with new image gc PR (https://github.com/kubernetes/kubernetes/pull/27199)
1. container gc policy should always run (will not be launched from eviction, tbd who does that)
1. this means kill pod is fine for all eviction code paths since container gc will remove dead container
1. min reclaim support will just poll summary provider (derek will do follow-on)
1. need to know if imagefs is same device as rootfs from summary (derek follow-on)
