Add the option to enable default Pod Security Configuration (#9017) 
* Add the option to enable default Pod Security Configuration

Enable Pod Security in all namespaces by default with the option to
exempt some namespaces. Without the change only namespaces explicitly
configured will receive the admission plugin treatment.

* Fix the PR according to code review comments

* Revert the latest changes

- leave the empty file when kube_pod_security_use_default, but add comment explaining the empty file
- don't attempt magic at conditionally adding PodSecurity to kube_apiserver_admission_plugins_needs_configuration

Allow "openSUSE Tumbleweed" to be run (#9072) 
The commit 1ce2f04 tried to merge multiple SUSE OS checks including
"openSUSE Leap" and "openSUSE Tumbleweed" into a single SUSE, but
that was a perfect change.
Then the commit c16efc9 tried to fix it for "openSUSE Leap", but it
didn't take care of "openSUSE Tumbleweed".
Then this adds "openSUSE Tumbleweed" to the OS check.

Revert "Set exact user for Kubelet services" (#8872) 
This reverts commit e375678674.

The workaround of explicitly specifying root for the kubelet unit was
for pulling images from private registry. Kubernetes now have a
dedicated mechanism with imagePullSecret.
