Move to a structured status for dynamic kubelet config
This PR updates dynamic Kubelet config to use a structured status, rather than a node condition. This makes the status machine-readable, and thus more useful for config orchestration.
Fixes: #56896
```release-note
The status of dynamic Kubelet config is now reported via Node.Status.Config, rather than the KubeletConfigOk node condition.

apimachinery: move schema reference object into smp patcher
The schema reference object is only used in the strategic merge patch code path. This PR moves the creation there.
This PR is a preparation to make the patcher compatible with the UnstructuredObjectConverter without internal types. It will allow us to return an error on missing kinds at https://github.com/kubernetes/kubernetes/pull/63830#discussion_r188171025.

apiserver: Fail if dry-run query param is specified
Adds a dry-run query parameter now that does nothing but reject the request. The sooner we have this check in master, the safer it will be for clients to send dry-run requests that are not going to be applied nonetheless.
```release-note
Create a new `dryRun` query parameter for mutating endpoints. If the parameter is set, then the query will be rejected, as the feature is not implemented yet. This will allow forward compatibility with future clients; otherwise, future clients talking with older apiservers might end up modifying a resource even if they include the `dryRun` query parameter.

**Release note**:
```release-note
The `PriorityClass` API is promoted to `scheduling.k8s.io/v1beta1`
```
**What this PR does / why we need it**:
The sample-controller makes extensive use of various mechanisms
available in the client-go library. For writing custom controllers/operators
it will be helpful if there is precise description of how the
client-go library works and how/where it interfaces with
custom controller code.
This patch adds documentation that sheds light on how (parts) of the
client-go library work and its interaction-points with
controller code. The documentation and the diagram comes from [1],
(link included here for reference purpose).

**Release note**:
```release-note
CustomResourceDefinitions Status subresource now supports GET and PATCH
```
Currently it is only possible to have one group of checks which must all pass for the handler to report success.
Allowing multiple paths for these checks allows use of the same machinery for other kinds of checks, i.e. readiness.
