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

* docs(hardening): add SeccompDefault admission plugin to kubelet feature gates

* fix(kubelet-config): enable config through kubelet_feature_gates

* feat(kubelet): add kubelet_seccomp_default variable

The commit 1ce2f04f 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 c16efc9a 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.
