Don't fail fast if LoadBalancer section is missing
**What this PR does / why we need it**:
We should allow scenarios where cinder can be used even if the
operator does not want to use the openstack load balancer. So
let's warn in the beginning if subnet-id is missing but fail only
if they try to use the load balancer

additional backoff in azure cloudprovider
Fixes#48971
**What this PR does / why we need it**:
We want to be able to opt in to backoff retry logic for kubelet-originating request behavior: node IP address resolution and node load balancer pool membership enforcement.
**Special notes for your reviewer**:
The use-case for this is azure cloudprovider clusters with large node counts, especially during cluster installation, or other scenarios when lots of nodes come online at once and attempt to register all resources with the backend API. To allow clusters at scale more control over the API request rate in-cluster, backoff config has the ability to meaningful slow down this rate, when appropriate.
**Release note**:
```additional backoff in azure cloudprovider
```

Restrict the visibility of two generated packages in pkg/client/
These two packages are deprecated. Please use the client-go copy of these two packages.
Currently staging/copy.sh copied these two packages to client-go. I'll send follow-up PRs to let code-gen output to client-go directly and remove these two packages. The purpose of this PR is to prevent more imports of these packages while I refactor the codegen.

azure: acr: support MSI with preview ACR with AAD auth
**What this PR does / why we need it**:
The recently added support for Managed Identity in Azure (#48854) was incompatible with automatic ACR docker credential integration (#48980).
This PR resolves that, by leveraging a feature available in Preview regions, on new managed clusters with support for AAD `access_token` authentication.
Notes:
* This includes code copied from [Azure/acr-docker-credential-helper](https://github.com/Azure/acr-docker-credential-helper). I copied the MIT license from that project and added a copyright line for Microsoft on it. (but one of the hack/verify-* scripts requires the Kubernetes copyright header. So there are two copyright headers in the file now...)
* Eventually this should vendor [Azure/acr-docker-credential-helper](https://github.com/Azure/acr-docker-credential-helper) when it exposes the right functionality.
* This includes a small, non-function-impacting workaround for a temporary service-side bug.

**Special notes for your reviewer**:
Please don't LGTM it without reviewing the `azure_acr_helper.go` file's license header...

*: remove --insecure-allow-any-token option
~Since the authenticator is still used in e2e tests, don't remove
the actual package. Maybe a follow up?~
edit: e2e and integration tests have been switched over to the tokenfile
authenticator instead.
```release-note
The --insecure-allow-any-token flag has been removed from kube-apiserver. Users of the flag should use impersonation headers instead for debugging.

Restore cAdvisor prometheus metrics to the main port
But under a new path - `/metrics/cadvisor`. This ensures a secure port still exists for metrics while getting the benefit of separating out container metrics from the kubelet's metrics as recommended in the linked issue.
Fixes#48483
```release-note-action-required
Restored cAdvisor prometheus metrics to the main port -- a regression that existed in v1.7.0-v1.7.2
cAdvisor metrics can now be scraped from `/metrics/cadvisor` on the kubelet ports.
Note that you have to update your scraping jobs to get kubelet-only metrics from `/metrics` and `container_*` metrics from `/metrics/cadvisor`

Implement equivalence cache by caching and re-using predicate result
The last part of #30844, I opened a new PR instead of overwrite the old one because we changed some basic assumption by allowing invalidating equivalence cache item by individual predicate.
The idea of this PR is based on discussion in https://github.com/kubernetes/kubernetes/issues/32024
- [x] Pods belong to same controllerRef considered to be equivalent
- [x] ` podFitsOnNode` will use cached predicate result if it's available
- [x] Equivalence cache will be updated when if a fresh new predicate is done
- [x] `factory.go` will invalid specific predicate cache(s) based on the object change
- [x] Since `schedule` and `bind` are async, we need to optimistically invalid affected cache(s) before `bind`
- [x] Fully unit test of affected files
- [x] e2e test to verify cache update/invalid workflow
- [x] performance test results
- [x] Some nits fixes related but expected to result in `needs-rebase` so they are split to: #36060#35968#37512
