Make selector immutable for v1beta2 deployment, replicaset and daemonset prior update
**What this PR does / why we need it**:

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

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.

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:

**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.

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
