Scheme conversion should support unstructured conversion natively to
allow going from unstructured to typed and back. It is not a higher
level responsibility to do that conversion because the scheme is the
only one who knows what types it supports.

Workloads V1
**What this PR does / why we need it**: This PR promotes the Deployment, ReplicaSet, and DaemonSet StatefulSet, ControllerRevision kinds to the apps/v1 group version.
https://github.com/kubernetes/features/issues/353
**Special notes for your reviewer**:
There will be at least two followups to this PR. The first to add a scale sub-resource when the correct location is resolved, and the second to deal with Conditions in the workloads API.
While it would have been preferable to move the kinds individually providing a lesser burden on reviewers, this proved impracticable due to the intricacies of version resolution in kubectl for objects of the different kinds in the same group.
```release-note
DaemonSet, Deployment, ReplicaSet, and StatefulSet have been promoted to GA and are available in the apps/v1 group version.

output empty creationTimestamp as null
**Release note**
```release-note
NONE
```
Updates the value of the `creationTimestamp` field to be `null`
when empty, to keep parity between it and `deletionTimestamp`.
Adds a round-trip test to ensure that unstructured objects containing
empty metadata fields are able to be re-converted back into internal
or external objects. Prior to the proposed patch in this PR, an
unstructured object whose `.metadata.creationTimestamp` value had
been set through the metadata accessor to an empty value
(`metav1.Time{}` in this case), was unable to be re-converted to an
internal or external type using the runtime decoder. Conversion would
fail with the error:
```
unstructured_test.go:177: FromUnstructured failed: parsing time "" as "2006-01-02T15:04:05Z07:00": cannot parse "" as "2006"
```

allow windows mount path
**What this PR does / why we need it**:
Currently mount path onlly allow Linux absolute path, allow windows mount path in this PR.
This code snippet in kubelet will run in both Linux and Windows, so use IsAbs func to tell whether it's a absolute path is not sufficient as for k8s windows cluster, the master is Linux and agent is Windows node.
**Special notes for your reviewer**:
The example pod with mount path is like below:
```
---
kind: Pod
apiVersion: v1
metadata:
name: pod-uses-shared-hdd-5g
labels:
name: storage
spec:
containers:
- image: microsoft/iis

ScaleIO - Ability to specify Secret's name and namespace
**What this PR does / why we need it**:
This PR is to decouple the ScaleIO secret from the same namespace as that of the StorageClass/PVC/PV that uses it (#53619). Currently, authorized non-admin k8s user, who creates volumes, may end up having unauthorized access to ScaleIO secret information. This PR introduces secret parameter that allows specification of secret's namespace.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#53619
**Release note**:
```release-note
ScaleIO persistent volumes now support referencing a secret in a namespace other than the bound persistent volume claim's namespace; this is controlled during provisioning with the `secretNamespace` storage class parameter; StoragePool and ProtectionDomain attributes no longer defaults to the value `default`

Refactor RBD volume
Refactor RBD Volume Persistent Volume Spec so RBD PV's SecretRef
allows referencing a secret from a persistent volume in any namespace.
This allows locating credentials for persistent volumes in namespaces
other than the one containing the PVC.
Closes#54432
```release-note
RBD Persistent Volume Sources can now reference User's Secret in namespaces other than the namespace of the bound Persistent Volume Claim

Polymorphic Scale Client
This PR introduces a polymorphic scale client based on discovery information that's able to scale scalable resources in arbitrary group-versions, as long as they present the scale subresource in their discovery information.
Currently, it supports `extensions/v1beta1.Scale` and `autoscaling/v1.Scale`, but supporting other versions of scale if/when we produce them should be fairly trivial.
It also updates the HPA to use this client, meaning the HPA will now work on any scalable resource, not just things in the `extensions/v1beta1` API group.
**Release note**:
```release-note
Introduces a polymorphic scale client, allowing HorizontalPodAutoscalers to properly function on scalable resources in any API group.

Previously, we did not have custom code for fuzzing label selectors.
Anything that used a label selector (like Scale) had to manually bypass
fuzzing the selector, or write its own fuzzer. This introduces a fuzzer
for label selectors which generates random correct selectors with random
keys and values.
