part of #62002

split up the huge set of flags into smaller option structs
**What this PR does / why we need it**:
To make generic, we do following work:
1. Spliting `KubeControllerManagerConfiguration` in kube-controller-manager and cloud-controller-manager into fewer smaller struct options order by controller, and modify relative flag. Also part of #59483.
2. Spliting `componentconfig` in controller-manager into fewer smaller config order by controller too.
All works follow #59582, using `option+config` logic.

Private mount propagation
This PR changes the default mount propagation from "rslave" (newly added in 1.10) to "private" (default in 1.9 and before). "rslave" as default causes regressions, see below.
Value `"None"` has to be added to `MountPropagationMode` enum in API ("I don't want any propagation at all"), which translates to "private" on Linux. [We did not have use cases for it](https://github.com/kubernetes/community/pull/659#discussion_r131454319), but we have them now.
**Which issue(s) this PR fixes**
Fixes#62397, fixes#62396
**Special notes for your reviewer**:
CRI already has an option for private mount propagation in volumes, however it's called "PRIVATE", while Kubernetes API value is "None". I did not change PRIVATE to NONE to keep the interface stable. See `kubelet_pods.go`.
**Release note**:
```release-note
Default mount propagation has changed from "HostToContainer" ("rslave" in Linux terminology) to "None" ("private") to match the behavior in 1.9 and earlier releases. "HostToContainer" as a default caused regressions in some pods.

fix local volume absolute path issue on Windows
**What this PR does / why we need it**:
remove IsAbs validation on local volume since it does not work on windows cluster, Windows absolute path `D:` is not allowed in local volume, the [validation](https://github.com/kubernetes/kubernetes/blob/master/pkg/apis/core/validation/validation.go#L1386) happens on both master and agent node, while for windows cluster, the master is Linux and agent is Windows, so `path.IsAbs()` func will not work all in both nodes.
**Instead**, this PR use `MakeAbsolutePath` func to convert `local.path` value in kubelet, it supports both linux and windows styple.

Resources prefixed with *kubernetes.io/ should remain unscheduled if they are not exposed on the node.
Currently, resources prefixed with `*kubernetes.io/` get scheduled to any
node whether it's exposing that resource or not.
On the other hand, resources prefixed with `someother.domain/` don't get
scheduled to a node until that node is exposing that resource (or if the
resource is ignored because of scheduler extender).
This commit brings the behavior of `*kubernetes.io/` prefixed resources in
line with other extended resources and they will remain unscheduled
until some node exposes these resources.
Fixes#50658
```release-note
Pods requesting resources prefixed with `*kubernetes.io` will remain unscheduled if there are no nodes exposing that resource.

node authorizer sets up access rules for dynamic config

Automatically add system critical priority classes at cluster boostrapping
**What this PR does / why we need it**:
We had two PriorityClasses that were hardcoded and special cased in our code base. These two priority classes never existed in API server. Priority admission controller had code to resolve these two names. This PR removes the hardcoded PriorityClasses and adds code to create these PriorityClasses automatically when API server starts.
