Prior to this patch, this fails because the skipnonappliedfieldmanager
uses the `objectcreater` (aka `*runtime.Scheme`) to create a new object
for which it never sets the GVK. In the case of
`*unstructured.Unstructured`, the GVK can not be derived from the object
itself so the operation would subsequently fail [here][0] with an
```
Object 'Kind' is missing in 'unstructured object has no kind'
```
error. Fix this by explicitly setting the GVK in case of unstructured.

In controller-runtime it is generally not expected to do any sort of
scheme registration if unstructured.Unstructured is used. To make this
work in the fakeclient, the fakeclient will register unstructured to
scheme if the scheme doesn't recognize the GVK.
This currently doesn't work with the `ManagedFieldsObjectTracker` as it
never reloads the scheme. This change makes it reload the scheme in an
inefficient but simple manner, which should be good enough for unit
tests.

This removes a dependency from generated applyconfigurations to a testing
package. To do this, the type converter in the testing package has been
moved out to the apimachinery package and the utilities the converter
depend on have been reorganized.

This adds a generic implementation of a fake clientset, and uses it to
replace the template code in generated fake clientsets for the default
methods. The templates are preserved as-is (or as close as they can
be) for use in extensions, whether for resources or subresources.
Fake clientsets with no extensions are reduced to their main getter,
their specific struct, and their constructor. All method
implementations are provided by the generic implementation. The
dedicated struct is preserved to allow extensions and expansions to be
defined where necessary.
Instead of handling the variants (with/without list, apply) with a
complex sequence of if statements, build up an index into an array
containing the various declarations.
Similarly, instead of calling different action constructors for
namespaced and non-namespaced clientsets, assume the current behaviour
of non-namespaced action creation (equivalent to creating a namespaced
action with an empty namespace) and document that assumption in the
action implementation.

The canonical import for json-patch v4 is
gopkg.in/evanphx/json-patch.v4 (see
https://github.com/evanphx/json-patch/blob/master/README.md#get-it for
reference).
Using the v4-specific path should also reduce the risk of unwanted v5
upgrade attempts, because they won't be offered as automated upgrades
by dependency upgrade management tools, and they won't happen through
indirect dependencies (see
https://github.com/kubernetes/kubernetes/pull/120327 for context).

The fake clientset used a slice to store each kind of objects, it's
quite slow to init the clientset with massive objects because it checked
existence of an object by traversing all objects before adding it, which
leads to O(n^2) time complexity. Also, the Create, Update, Get, Delete
methods needs to traverse all objects, which affects the time statistic
of code that calls them.
This patch changed to use a map to store each kind of objects, reduced
the time complexity of initializing clientset to O(n) and the Create,
Update, Get, Delete to O(1).
For example:
Before this patch, it took ~29s to init a clientset with 30000 Pods,
and 2~4ms to create and get an Pod.
After this patch, it took ~50ms to init a clientset with 30000 Pods,
and tens of µs to create and get an Pod.

In other parts of the system (notably in RBAC rules), the "resource/subresource" notation is common to specify an explicit subresource. This makes this notation available to tests that use the `Matches` function on client actions as well.
Backwards compatibility is kept by ignoring the `Subresource` field if no specific subresource is defined in the resource string itself.

`Get` method within the fake clientset returns an object that would not be normally returned when using the real clientset. Reproducer:
```go
package main
import (
v1 "k8s.io/api/core/v1"
metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
"k8s.io/client-go/kubernetes/fake"
)
func main () {
cm := &v1.ConfigMap{
ObjectMeta: metav1.ObjectMeta{Namespace: metav1.NamespaceSystem, Name: "cm"},
}
client := fake.NewSimpleClientset(cm)
obj, err := client.CoreV1().ConfigMaps("").Get("", metav1.GetOptions{})
if err != nil {
panic(err)
}
fmt.Printf("obj: %#v\n", obj)
}
```
stored under `test.go` of `github.com/kubernetes/kubernetes` (master HEAD) root directory and ran:
```sh
$ go run test.go
obj: &v1.ConfigMap{TypeMeta:v1.TypeMeta{Kind:"", APIVersion:""}, ObjectMeta:v1.ObjectMeta{Name:"cm", GenerateName:"", Namespace:"kube-system", SelfLink:"", UID:"", ResourceVersion:"", Generation:0, CreationTimestamp:v1.Time{Time:time.Time{wall:0x0, ext:0, loc:(*time.Location)(nil)}}, DeletionTimestamp:(*v1.Time)(nil), DeletionGracePeriodSeconds:(*int64)(nil), Labels:map[string]string(nil), Annotations:map[string]string(nil), OwnerReferences:[]v1.OwnerReference(nil), Finalizers:[]string(nil), ClusterName:"", ManagedFields:[]v1.ManagedFieldsEntry(nil)}, Data:map[string]string(nil), BinaryData:map[string][]uint8(nil)}
```
As you can see fake clientset with a "test" configmap is created. When getting the object through the clientset back, I intentionally set the object name to an empty string. I would expect to get an error saying config map "" was not found. However, I get "test" configmap instead.
Reason for that is inside implementation of `filterByNamespaceAndName` private function:
```go
func filterByNamespaceAndName(objs []runtime.Object, ns, name string) ([]runtime.Object, error) {
var res []runtime.Object
for _, obj := range objs {
acc, err := meta.Accessor(obj)
if err != nil {
return nil, err
}
if ns != "" && acc.GetNamespace() != ns {
continue
}
if name != "" && acc.GetName() != name {
continue
}
res = append(res, obj)
}
return res, nil
}
```
When `name` is empty, `name != "" && acc.GetName() != name` condition is false and thus `obj` is consider as a fit.

When a client requests a PartialObjectMetadata returned from the
ObjectReaction type, if the object has a GVK set use that instead
of what the schema returns, since the majority of clients getting
partial object metadata will be doing so using the metadata client
or server side conversion.

Only Unstructured objects worked (because unstructured implicitly
clears the .Object map when Unmarshal is called). We must reset
obj before we attempt to unmarshal into it.

Currently the fake client will return a default empty Object when a
Patch action is submitted on a missing Object. The correct behavior is to
instead propagate the NotFound error.

This commit fixes a bug in the client-go/testing fixture whereby a
watcher would fire twice for objects with no namespace.

The FakeWatcher allows sends on the result channel after it's closed,
for example calling Stop() then Add() will panic. RaceFreeFakeWatcher
checks whether the watcher is stopped before attempting to send. It also
panics instead of blocking when the result channel is full.
