Stop() for Ticker to enable leak-free code
**What this PR does / why we need it**:
I wanted to use the clock package but the `Ticker` without a `Stop()` method is a deal breaker for me.

explicit kubelet config key in Node.Spec.ConfigSource.ConfigMap
This makes the Kubelet config key in the ConfigMap an explicit part of
the API, so we can stop using magic key names.
As part of this change, we are retiring ConfigMapRef for ConfigMap.
```release-note
You must now specify Node.Spec.ConfigSource.ConfigMap.KubeletConfigKey when using dynamic Kubelet config to tell the Kubelet which key of the ConfigMap identifies its config file.

category expansion can only come from the server
A couple release ago we moved category expansion to the server instead of hardcoding it in the client. Similar to restmappings, there is no valid client-side expansion anymore, so this removes the code that hardcoded the list and moves the category expansion to the same package as our discovery based restmappers.

Exclude keys containing empty patches in the final patch
**What this PR does / why we need it**:
This minimizes the 3-way JSON merge patch generated when calculating the patch necessary to send to the server. It does this by removing empty maps created from deleting keys in the keepOrDeleteNullInObj method.
This is not only a slight performance improvement (less PATCH requests) but also necessary when working with custom resources that have RBAC restrictions.

apiextensions: allow "required" at root with status subresource
In the subresources alpha we intentionally disallowed anything than `properties` at the root of the validation schema in order to allow us to project it to the .status subtree. By doing this we also disallowed `required` at the root which is necessary to enforce e.g. a spec to be set. This PR fixes this.
Moreover, it fixes that the restriction is only enforced when the status subresource is actually enabled. Before this PR we were enforcing the restriction as soon as the feature gate was enabled, leading to a backwards incompatible change.
```release-note
Allow "required" to be used at the CRD OpenAPI validation schema when the /status subresource is enabled.
```
There was an issue reporting the bug. But cannot find it.

kubectl get CRD resources with --server-print=true column name error
**What this PR does / why we need it**:
Here's a bunch of kubectl get command execution and their outputs.
my-crd is the user-define CRD resource.
1.
```
kubectl get pod --all-namespaces --server-print=true
NAMESPACE NAME READY STATUS RESTARTS AGE
test-ns test-pod 1/1 running 1 15m
```
2.
```
kubectl get my-crd --all-namespaces --server-print=false
NAMESPACE NAME AGE
test-ns test-crd 21m
```
3.
```
kubectl get my-crd --all-namespaces --server-print=true
NAMESPACE NAME CREATED AT
test-ns test-crd 21m
```
Here's the problem
1. Example 3 isn't consistent with example 1 and 2
2. CREATED AT 21m doesn't make sense
This patch fix this.

remove redundant runtime.GOMAXPROCS
Since golang 1.5, `By default, Go programs run with GOMAXPROCS set to the number of cores available;`
If env `GOMAXPROCS `, it uses default `runtime.NumCPU()`. So set again is redundant.

the output looks like:

Notice that the column CREATED AT 2m makes no sense.
The correct column name here should be AGE.
Which keeps the same with the situation when --server-print=false

Cache preferred resources, use in kubectl resource name autocomplete

Fixes https://github.com/kubernetes/kubectl/issues/357
Alternative to #61928
* starts to unify preferred resource logic on top of ServerGroups()/ServerResourcesForGroupVersion() methods
* allows indicating a cached list of resources is acceptable when calling `kubectl api-resources` (default is still to rediscover)
* uses `kubectl api-resources` in bash completion
