apimachinery: unify accessors to not deepcopy

The Get/SetOwnerReferences accessor funcs do deepcopies, in contrast to all other accessor funcs of metav1.ObjectMeta. For unstructured.Unstructured we naturally do deepcopies. 

In other words: the interface does guarantee neither the first nor the second. 

This PR documents this and remove the unneccessary deepcopy for owner references (which leads to huge heap allocation e.g. in the DaemonSet controller).

This is for post-1.11. **do not assign a milestone**.

```dev-release-note
The metav1.ObjectMeta accessor does not deepcopy owner references anymore. In general, the accessor interface does not enforce deepcopy nor does it forbid it (e.g. for unstructured.Unstructured).
```

External Repository Staging Area

This directory is the staging area for packages that have been split to their own repository. The content here will be periodically published to respective top-level k8s.io repositories.

Repositories currently staged here:

The code in the staging/ directory is authoritative, i.e. the only copy of the code. You can directly modify such code.

Using staged repositories from Kubernetes code

Kubernetes code uses the repositories in this directory via symlinks in the vendor/k8s.io directory into this staging area. For example, when Kubernetes code imports a package from the k8s.io/client-go repository, that import is resolved to staging/src/k8s.io/client-go relative to the project root:

// pkg/example/some_code.go
package example

import (
  "k8s.io/client-go/dynamic" // resolves to staging/src/k8s.io/client-go/dynamic
)

Once the change-over to external repositories is complete, these repositories will actually be vendored from k8s.io/<package-name>.
