update scheduler to return structured errors instead of process exit
The scheduler Run method returns an error that is properly handled at higher levels. Instead of existing the process, we should return the error and handle it at higher level logic to allow testing of error conditions and composition of commands. The changes are relatively minor.

Add PVCRef to VolumeStats
**What this PR does / why we need it**:
For pod volumes that reference a PVC, add a PVCRef to the corresponding
volume stat. This allows metrics to be indexed/queried by PVC name
which is more user-friendly than Pod reference

Fix prefixing bug in import verifier
In order to check if an import is of an allowed tree, we need to check
that the import is either literally to the base of the tree or that the
import is below the tree (the import, suffixed with `/`, should be a
prefix) instead of checking simply that the import is a prefix of the
allowed tree, as that causes issues with packages that are prefixes of
each other, like `k8s.io/api` and `k8s.io/apimachinery`.

Kubectl to use http caching to cache openapi responses from the server
**What this PR does / why we need it**:
This PR is trying to address the problems raised in #50254
> * uses a disk-based cache that is not safe between processes (does not use atomic fs operations)
> * writes get/list responses to disk that should not be cached (like kubectl get secrets)
> * is vulnerable to partially written cache responses being used as responses to future requests
> * breaks uses of the client transport that make use of websockets
> * defaults to enabling the cache for any client builder using RecommendedConfigOverrideFlags or DefaultClientConfig which affects more components than just kubectl
All of these points are addressed by this pull-request:
1. It now uses atomic fs operations
2. Doesn't cache by default, only if requested by the client (and it's only done by openapi client)
3. Fixed because of atomic fs operations
4. Found the reason for the bug: Cache wrapper couldn't be unwrapped. I implemented the `WrappedRoundTripper` interface.
5. Since 2. is fixed, I think that should be fine

AWS: check validity of KSM key before creating a new encrypted disk.
AWS CreateVolume call does not check if referenced encryption key actually exists and returns a valid new AWS EBS volume even though an invalid key was specified. Later on it removes the EBS silently when its encryption fails.
To work around this buggy behavior we manually check that the key exists before calling CreateVolume.
Fixes#48438
/sig aws
Please review carefully. Can we safely assume that Kubernetes controller-manager can read encryption keys?
