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.

`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.

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.
Kubernetes-commit: bd268c9971efd4db46074a80e52ce765583e0787
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.
