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.

README.md

apiserver

Generic library for building a Kubernetes aggregated API server.

Purpose

This library contains code to create Kubernetes aggregation server complete with delegated authentication and authorization, kubectl compatible discovery information, optional admission chain, and versioned types. It's first consumers are k8s.io/kubernetes, k8s.io/kube-aggregator, and github.com/kubernetes-incubator/service-catalog.

Compatibility

There are NO compatibility guarantees for this repository, yet. It is in direct support of Kubernetes, so branches will track Kubernetes and be compatible with that repo. As we more cleanly separate the layers, we will review the compatibility guarantee. We have a goal to make this easier to use in the future.

Where does it come from?

apiserver is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apiserver. Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.

Things you should NOT do

  1. Directly modify any files under pkg in this repo. Those are driven from k8s.io/kubernetes/staging/src/k8s.io/apiserver.
  2. Expect compatibility. This repo is changing quickly in direct support of Kubernetes and the API isn't yet stable enough for API guarantees.
