**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.

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).

add reconcile command to kubectl auth
This pull exposes the RBAC reconcile commands through `kubectl auth reconcile -f FILE`. When passed a file which contains RBAC roles, rolebindings, clusterroles, or clusterrolebindings, it will compute covers and add the missing rules.
The logic required to properly "apply" rbac permissions is more complicated that a json merge since you have to compute logical covers operations between rule sets. This means that we cannot use `kubectl apply` to update rbac roles without risking breaking old clients (like controllers).
To solve this problem, RBAC created reconcile functions to use during startup for "stock" roles. We want to offer this power to users who are running their own controllers and extension servers.
This is an intersection between @kubernetes/sig-auth-misc and @kubernetes/sig-cli-misc

Mount propagation in kubelet
Together with #45724 it implements mount propagation as proposed in https://github.com/kubernetes/community/pull/659
There is:
- New alpha annotation that allows user to explicitly set propagation mode for each `VolumeMount` in pod containers (to be replaced with real `VolumeMount.Propagation` field during beta) + validation + tests. "Private" is the default one (= no change to existing pods).
I know about proposal for real API fields for alpha feature in https://docs.google.com/document/d/1wuoSqHkeT51mQQ7dIFhUKrdi3-1wbKrNWeIL4cKb9zU/edit, but it seems it's not implemented yet. It would save me quite lot of code and ugly annotation.
- Updated CRI API to transport chosen propagation to Docker.
- New `kubelet --experimental-mount-propagation` option to enable the previous bullet without modifying types.go (worked around with changing `KubeletDeps`... not nice, but it's better than adding a parameter to `NewMainKubelet` and removing it in the next release...)
```release-note
kubelet has alpha support for mount propagation. It is disabled by default and it is there for testing only. This feature may be redesigned or even removed in a future release.

add information for subresource kind determination
xref https://github.com/kubernetes/kubernetes/issues/38810https://github.com/kubernetes/kubernetes/issues/38756
Polymorphic subresources usually have different groupVersions for their discovery kinds than their "native" groupVersions. Even though the APIResourceList shows the kind properly, it does not reflect the group or version of that kind, which makes it impossible to unambiguously determine if the subresource matches you and it is impossible to determine how to serialize your data. See HPA controller.
This adds an optional Group and Version to the discovery doc, which can be used to communicate the "native" groupversion of an endpoint. Doing this does not preclude fancier contenttype negotiation in the future and doesn't prevent future expansion from indicating equivalent types, but it does make it possible to solve the problem we have today or polymorphic categorization.
@kubernetes/sig-api-machinery-misc @smarterclayton
@cheftako since @lavalamp is out.
```release-note
Adds optional group and version information to the discovery interface, so that if an endpoint uses non-default values, the proper value of "kind" can be determined. Scale is a common example.

Paramaterize `stickyMaxAgeMinutes` for service in API
**What this PR does / why we need it**:
Currently I find `stickyMaxAgeMinutes` for a session affinity type service is hard code to 180min. There is a TODO comment, see
https://github.com/kubernetes/kubernetes/blob/master/pkg/proxy/iptables/proxier.go#L205
I think the seesion sticky max time varies from service to service and users may not aware of it since it's hard coded in all proxier.go - iptables, userspace and winuserspace.
Once we parameterize it in API, users can set/get the values for their different services.
Perhaps, we can introduce a new field `api.ClientIPAffinityConfig` in `api.ServiceSpec`.
There is an initial discussion about it in sig-network group. See,
