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?
```release-note
aws: Kubernetes now checks existence of provided KSM (Key Management Service) key before creating an encrypted AWS EBS.

allow disabling the scheduler port
Unlike the `kube-apiserver`, the scheduler can function without exposing a status port. This provides the option to disable it by explicitly passing a `-1`. This does not change default behavior.

Switch away from gcloud deprecated flags in compute resource listings
**What is fixed**
Remove deprecated `gcloud compute` flags, see linked issue.
**Which issue this PR fixes**:
fixes#49673
**Special notes for your reviewer**:
The change in `gcloudComputeResourceList` in `test/e2e/framework/ingress_utils.go` isn't strictly needed as currently no affected resources are called on within that file, however the function has the _potential_ to access affected resources so I covered it as well. Happy to change if deemed unnecessary.

Add upgrades tests for kube-proxy daemonset migration path
**What this PR does / why we need it**:
From #23225, this is a part of setting up CIs to validate the kube-proxy migration path (static pods -> daemonset and reverse).
The other part of the works (adding real CIs that run these tests) will be in a separate PR against [kubernetes/test-infra](https://github.com/kubernetes/test-infra).
Though this is currently blocked by #50705.

- The `ubuntu-init-docker.yaml` is copied from `cos-init-docker.yaml` with the following changes needed by Ubuntu. This change is temporary -- we will remove the script and the tests once we know the performance of using the pre-built Docker 1.12 on Ubuntu.

Implement IPVS-based in-cluster service load balancing
**What this PR does / why we need it**:
Implement IPVS-based in-cluster service load balancing. It can provide some performance enhancement and some other benefits to kube-proxy while comparing iptables and userspace mode. Besides, it also support more sophisticated load balancing algorithms than iptables (least conns, weighted, hash and so on).

**Special notes for your reviewer**:
* Since the PR is a bit large, I splitted it and move the commits related to ipvs util pkg to PR #48994. Hopefully can make it easier to review.

adding validations on kubelet starting configurations
**What this PR does / why we need it**:
I found some validations of kubelet starting options were missing when I was creating a custom cluster from scratch. The kubelet does not check invalid configurations on `--cadvisor-port`, `--event-burst`, `--image-gc-high-threshold`, etc. I have added some validations in kubelet like validations in `cmd/kube-apiserver/app/options/validation.go`.

Add --append-hash flag to kubectl create configmap/secret
**What this PR does / why we need it**:
Specifying this new flag will automatically hash the configmap/secret
contents with sha256 and append the first 40 hex-encoded bits of the
hash to the name of the configmap/secret. This is especially useful for
workflows that generate configmaps/secrets from files (e.g.
--from-file).
See this Google doc for more background:
https://docs.google.com/document/d/1x1fJ3pGRx20ujR-Y89HUAw8glUL8-ygaztLkkmQeCdU/edit
**Release note**:
```release-note
Adds --append-hash flag to kubectl create configmap/secret, which will append a short hash of the configmap/secret contents to the name during creation.
