Remove subnet size restriction for IPv6
RangeSize was restricting IPv6 subnets to a /66 due to the
logic using a uint64. This is not practical for IPv6.
This change removes the /64 restriction, but also sets a limit
on the range that can be allocated, so that the bitmap will not grow too large.
**What this PR does / why we need it**:
This PR removes the /66 restriction in ipallocator for IPv6. It is not practical to restrict
IPv6 to /66. Currently a /64 or /48 is not allowed. The problem with removing the restriction is
the bitmap that tracks the subnets can grow really large, so a limit
on the max size of the subnet was set to 65536.
Setting the max size will have a side-effect with larger subnets that the allocator
will allocate in a smaller section of IP's, this will need to be addressed in a follow-on PR.

**Special notes for your reviewer**:
**Release note**:
```release-note-none
```
The registry abstraction is unnecessary and adds direct coupling to the
core types. By using a wrapper, we carry through the default
implementations of the non-mutating operations. The DeleteCollection
method is explicitly patched out since it cannot be correctly
implemented on the storage currently.
As a result, TableConvertor is now exposed.
A few other minor refactorings
* Corrected the case of some variables
* Used functions instead of methods for several helper methods
* Removed the legacy Deleter - service was the only remaining consumer

Introduce PodSecurityPolicy in the policy/v1beta1 API group
Types/constants are completely the same as in `extensions/v1beta1` except that they are located outside of the `extensions` API group.
**What this PR does / why we need it**:
This is the first step for migrating PSP-related stuff away of `extensions` group. See #43214 for more information.

$ cat restricted2.yaml
apiVersion: policy/v1beta1

...
$ kubectl create -f restricted.yaml
podsecuritypolicy "restricted2" created
$ kubectl get psp restricted2 -o yaml
apiVersion: extensions/v1beta1
kind: PodSecurityPolicy
...
```
**Release note**:
```release-note
The `PodSecurityPolicy` API has been moved to the `policy/v1beta1` API group. The `PodSecurityPolicy` API in the `extensions/v1beta1` API group is deprecated and will be removed in a future release.

Add NominatedNodeName field to PodStatus
**What this PR does / why we need it**:
Today, Scheduler uses an annotation called "nominated-node-name" to mark a preemptor Pod. This annotation helps scheduler know about the Pods that are destined to run on the nodes so that the resources made available by preemption is not allocated to a different Pod. In a recent discussion with @bgrant0607, we learned that we should change the annotation to a field as this field can be used by multiple schedulers and other components that may make scheduling-related decisions (descheduler, auto-scaler, kube-arbitrator, ...).

**What this PR does / why we need it**:

For core controllers, like `Deployment`, `DaemonSet`, `ReplicaSet`, and `StatefulSet`, changing the `DefaultGarbageCollectionPolicy` from `OrphanDependents` to `DeleteDependents` will make these objects consistent with the default behavior for all new objects.
For legacy API versions, the `DefaultGarbageCollectionPolicy` remains `OrphanDependents`.

The default garbage collection policy for Deployment, DaemonSet, StatefulSet, and ReplicaSet has changed from OrphanDependents to DeleteDependents when the deletion is requested through an `apps/v1` endpoint. Clients using older endpoints will be unaffected. This change is only at the REST API level and is independent of the default behavior of particular clients (e.g. this does not affect the default for the kubectl `--cascade` flag).
If you upgrade your client-go libs and use the `AppsV1()` interface, please note that the default garbage collection behavior is changed.
