Fixed detection of inaccessible AWS encryption key.
AWS provisioner now checks if created encrypted volume gets "Available" or it gets silently deleted by AWS because StorageClass referenced invalid (e.g. non-existing) KMS key for encryption.
This seems to be the only way how to detect such invalid key, because Kubernetes may not have enough permission to check if the key exists.
**Which issue(s) this PR fixes**
Fixes#62171
**Special notes for your reviewer**:
**Release note**:
```release-note
AWS now checks for validity of ecryption key when creating encrypted volumes. Dynamic provisioning of encrypted volume may get slower due to these checks.

sample-apiserver: Add RBAC roles and ClusterRoleBindings for Admission Webhooks
**What this PR does / why we need it**:
When you run the `sample-apiserver` using the [manifests provided in the artifacts directory](https://github.com/kubernetes/sample-apiserver/tree/master/artifacts/example), you will get the following errors, related to insufficient permissions to list Namespaces and Admission Webhooks:

Remove optimization from getWork in resourcequota/controller.go
**What this PR does / why we need it**:
This change simplifies the code in
plugin/pkg/admission/resourcequota/controller.go by removing the
optimization in getWork that required the caller to NOT call
completeWork if getWork returns the empty list of work. BTW, the
caller was not obeying that requirement; now the caller's behavior
(which is unchanged) is right.

Narrow e2e pre-check on scheduler predicates
WaitForAllNodesHealthy actually checks for optional add-ons running on all nodes. The scheduler tests only care about node readiness, so just check for that.

Split scheduler latency metric to fine-grained steps
This splits the summary metric we recently added into finer steps. It should be very useful for performance experiments.
/cc @wojtek-t
fyi - @bsalamat @misterikkit
Strictly speaking this is a breaking change, but since this metric was added only ~week ago I think it should fine (we should port this change to 1.11).

This makes sure that github.com/Azure/azure-sdk-for-go has the dependency it
requires: as of v14.6.0, it has a constraint for github.com/satori/go.uuid to be
at 1.2.0 (or above).
This was introduced in https://github.com/Azure/azure-sdk-for-go/pull/979
(see discussion for rationale)
Since github.com/Azure/azure-sdk-for-go is the only consumer of
github.com/satori/go.uuid, there is no reason not to use the correct version.
This also prepares the ground for a future migration to dep.

Use actual etcd client for /healthz/etcd checks
* avoids redialing etcd on every health check (which makes slow DNS a false-positive healthz failure)
* ensures etcd TLS setup is correct (errors verifying the etcd API or sending client credentials manifest as healthz failures)
* ensures the etcd cluster is actually responsive
fixes#64909
```release-note
Etcd health checks by the apiserver now ensure the apiserver can connect to and exercise the etcd API
