Fix unstructured metadata accessors to respect omitempty semantics

Fixes #67541
Fixes #48211 
Fixes #49075
Follow up of #67562

`ObjectMeta` has fields with `omitempty` json tags. This means that when the fields have zero values, they should not be persisted in the object.

Before this PR, some of the metadata accessors for unstructured objects did not respect these semantics i.e they would persist a field even if it had a zero value.

This PR updates the accessors so that the field is removed from the unstructured object map if it contains a zero value.

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>.
