Rather than just looking for zone tags at the VM's Host level, traverse up the hierarchy.
This allows zone tags to be attached at host level, along with cluster, datacenter, root folder
and any inventory folders in between.

fix kubelet iptclient in ipv6 cluster

Support dry run in admission webhooks
**What this PR does / why we need it**:
Follow up to https://github.com/kubernetes/kubernetes/pull/66391
- [x] add DryRun to ```admission.k8s.io/v1beta1.AdmissionReview```
- [x] add DryRunnable to ```admissionregistration.k8s.io/v1beta1.(Valid|Mut)atingWebhookConfiguration```
- [x] add dry run support to (Valid|Mut)atingAdmissionWebhook
Includes all the api-changes outlined by https://github.com/kubernetes/community/pull/2387
/sig api-machinery
**Release note**:
```release-note
To address the possibility dry-run requests overwhelming admission webhooks that rely on side effects and a reconciliation mechanism, a new field is being added to admissionregistration.k8s.io/v1beta1.ValidatingWebhookConfiguration and admissionregistration.k8s.io/v1beta1.MutatingWebhookConfiguration so that webhooks can explicitly register as having dry-run support. If a dry-run request is made on a resource that triggers a non dry-run supporting webhook, the request will be completely rejected, with "400: Bad Request". Additionally, a new field is being added to the admission.k8s.io/v1beta1.AdmissionReview API object, exposing to webhooks whether or not the request being reviewed is a dry-run.

Fix unstructured metadata accessors to respect omitempty semantics
Fixes#67541Fixes#48211Fixes#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.
