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. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes # **Special notes for your reviewer**: **Release note**: ```release-note NONE ```
