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.

Log real file's name and line
**What this PR does / why we need it**:
Have correct location of emission in the logs
**Release note**:
pkg/kubectl/util/logs & staging/src/k8s.io/apiserver/pkg/util/logs
use `glog.info(...)` but this function is not made to be wrapped because
the underlying mechanism use a fixed call trace length to determine
where the log has been emited.
This results is having `logs.go:49` in the logs which is in the body
of the wrapper function and thus useless.
Instead use `glog.infoDepth(1, ...)` which tells the underlying mechanism
to go back 1 more level in the call trace to determine where the log
has been emitted.

Use sync.map to scale equiv class cache better
**What this PR does / why we need it**:
Change the current lock in first level ecache into `sync.Map`, which is known for scaling better than `sync. Mutex ` on machines with >8 CPUs
ref: https://golang.org/pkg/sync/#Map
And the code is much cleaner in this way.
5k Nodes, 10k Pods benchmark with ecache enabled in 64 cores VM:
```bash
// before
BenchmarkScheduling/5000Nodes/0Pods-64 10000 17550089 ns/op
// after
BenchmarkScheduling/5000Nodes/0Pods-64 10000 16975098 ns/op
```
Comparing to current implementation, the improvement after this change is noticeable, and the test is stable in 8, 16, 64 cores VM.
