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

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.

Feature gate initializers field
The metadata.initializers field should be feature gated and disabled by default while in alpha, especially since enforcement of initializer permission that keeps users from submitting objects with their own initializers specified is done via an admission plugin most clusters do not enable yet.
Not gating the field and tests caused tests added in https://github.com/kubernetes/kubernetes/issues/51429 to fail on clusters that don't enable the admission plugin.
This PR:
* adds an `Initializers` feature gate, auto-enables the feature gate if the admission plugin is enabled
* clears the `metadata.initializers` field of objects on create/update if the feature gate is not set
* marks the e2e tests as feature-dependent (will follow up with PR to test-infra to enable the feature and opt in for GCE e2e tests)
```release-note
Use of the alpha initializers feature now requires enabling the `Initializers` feature gate. This feature gate is auto-enabled if the `Initialzers` admission plugin is enabled.

Fix mergekey of initializers; Repair invalid update of initializers
Fix https://github.com/kubernetes/kubernetes/issues/51131
The PR did two things to make parallel patching `metadata.initializers.pending` possible:
* Add mergekey to initializers.pending
* Let the initializer admission plugin set the `metadata.intializers` to nil if an update makes the `pending` and the `result` both nil, instead of returning a validation error. Otherwise if multiple initializer controllers sending the patch removing themselves from `pending` at the same time, one of them will get a validation error.
```release-note
The patch to remove the last initializer from metadata.initializer.pending will result in metadata.initializer to be set to nil (assuming metadata.initializer.result is also nil), instead of resulting in an validation error.

Remove null -> [] slice hack
Closes#44593
When 1.6 added protobuf storage, the storage layer lost the ability to persist slice fields with empty but non-null values.
As a workaround, we tried to convert empty slice fields to `[]`, rather than `null`. Compressing `null` -> `[]` was just as much of an API breakage as `[]` -> `null`, but was hoped to cause fewer problems in clients that don't do null checks.
Because of conversion optimizations around converting lists of objects, the `null` -> `[]` hack was discovered to only apply to individual get requests, not to a list of objects. 1.6 and 1.7 was released with this behavior, and the world didn't explode. 1.7 documented the breaking API change that `null` and `[]` should be considered equivalent, unless otherwise noted on a particular field.
This PR:
* Reverts the earlier attempt (https://github.com/kubernetes/kubernetes/pull/43422) at ensuring non-null json slice output in conversion
* Makes results of `get` consistent with the results of `list` (which helps naive clients that do deepequal comparisons of objects obtained via list/watch and get), and allows empty slice fields to be returned as `null`
```release-note
Protobuf serialization does not distinguish between `[]` and `null`.
API fields previously capable of storing and returning either `[]` and `null` via JSON API requests (for example, the Endpoints `subsets` field) can now store only `null` when created using the protobuf content-type or stored in etcd using protobuf serialization (the default in 1.6+). JSON API clients should tolerate `null` values for such fields, and treat `null` and `[]` as equivalent in meaning unless specifically documented otherwise for a particular field.

Paramaterize `stickyMaxAgeMinutes` for service in API
**What this PR does / why we need it**:
Currently I find `stickyMaxAgeMinutes` for a session affinity type service is hard code to 180min. There is a TODO comment, see
https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/iptables/proxier.go#L205
I think the seesion sticky max time varies from service to service and users may not aware of it since it's hard coded in all proxier.go - iptables, userspace and winuserspace.
Once we parameterize it in API, users can set/get the values for their different services.
Perhaps, we can introduce a new field `api.ClientIPAffinityConfig` in `api.ServiceSpec`.
There is an initial discussion about it in sig-network group. See,

default field selectors
We have a lot of code around field selectors that doesn't add much value. Every gettable resources probably wants name and namespace by default and since they all use metav1 (today), we can assign that as a default. If we think we'll always have metav1 style name and namespace, then this makes a reasonable default and you can always set something different.
This removes cruft and avoids the risk of accidentally forgetting a field selector.

Remove incorrect patch-merge directives.
**What this PR does / why we need it**:
Directives were misplaced for the following types:
- MatchExpressions
- Taints
- Tolerations
Per the discussion in #46547, we cannot fix these because it would cause backwards-compatibility problems. Instead, remove the incorrect ones so they don't mislead users. This has no impact on behavior.

Updated gRPC vendoring to support Keep Alive
**What this PR does / why we need it**:
This PR bumps the version of the vendored version of gRPC from v1.0.4 to v1.5.1
This is needed as part of the Device Plugin API where we expect client and server to use the Keep alive feature in order to detect an error.
Unfortunately I had to also bump the version of `golang.org/x/text` and `golang.org/x/net`.

Add ReclaimPolicy field to StorageClass
fix https://github.com/kubernetes/kubernetes/issues/38192, enough people want this imo so going ahead and adding it according to initial suggested design
some considerations:
* No Recycle allowed, Retain (& Delete) only.
* Do we need to gate the field.
* E2E test where a Retain PV is dynamically provisioned is TODO if we agree we want this & this is the way to do it.
* Need a feature repo issue to track docs and stuff for 1.8
**Release note**:
```release-note
StorageClass has a new field to configure reclaim policy of dynamically provisioned PVs.
```
1. Clear the status of the CRD and set the Generation before creation.
2. While updating the CRD:
- ignore changes on status.
- increase Generation if spec changes.
3. Don't update objectmeta when status is updated.
- however, update finalizers. Without this, deletion will timeout.

Add metric for remaining lifetime of certificates authenticating requests
fixes#50778
When incoming requests to the API server are authenticated by a certificate, the expiration of the certificate can affect the validity of the authentication. With auto rotation of certificates, which is starting with kubelet certificates, the goal is to use shorter lifetimes and let the kubelet renew the certificate as desired. Monitoring certificates which are approaching expiration and not renewing would be an early warning sign that nodes are about to stop participating in the cluster.
**Release note**:
```release-note
Add new Prometheus metric that monitors the remaining lifetime of certificates used to authenticate requests to the API server.
```

Move List (the type) into metav1 but preserve the exposed type
Make a list something that other components can use without depending on the core API. This does not change the public API exposure of `List` (it is still in `v1`) but makes the interface common across both.
