Use the pre-built docker binaries on Ubuntu for benchmark tests
- Tested manually.
- 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).
**Which issue this PR fixes**
#17470#44063
**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.
```
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`.

Add Google cloud KMS service for envelope encryption transformer
This adds the required pieces which will allow addition of KMS based encryption providers (envelope transformer).
For now, we will be implementing it using Google Cloud KMS, but the code should make it easy to add support for any other such provider which can expose Decrypt and Encrypt calls.
Writing tests for Google Cloud KMS Service may cause a significant overhead to the testing framework. It has been tested locally and on GKE though.
Upcoming after this PR:
* Complete implementation of the envelope transformer, which uses LRU cache to maintain decrypted DEKs in memory.
* Track key version to assist in data re-encryption after a KEK rotation.
Development branch containing the changes described above: https://github.com/sakshamsharma/kubernetes/pull/4
Envelope transformer used by this PR was merged in #49350
Concerns #48522

```

Fix handling of APIserver errors when saving provisioned PVs.
When API server crashes *after* saving a provisioned PV and before sending
200 OK, the controller tries to save the PV again. In this case, it gets
AlreadyExists error, which should be interpreted as success and not as error.
Especially, a volume that corresponds to the PV should not be deleted in the
underlying storage.
Fixes#44372
