Fix kuttl tests on newer OpenShift versions

[razvan]

Description

Pre-requisite for https://github.com/stackabletech/issues/issues/564

Newer versions of OpenShift require namespaces created by kuttl to be annotated with a new label:

pod-security.kubernetes.io/enforce: "privileged"

This requires a new 00 step in each kuttl test case or a patched kuttl version as seen here.

Without this step we have exceptions such as:

Error from server (Forbidden): error when creating "STDIN": statefulsets.apps "openldap" is forbidden: openldap uses an inline volume provided by CSIDriver secrets.stackable.tech and namespace kuttl-test-huge-pika has a pod security enforce level that is lower than privileged

Acceptance criteria

• A new test step is executed at the beginning of each test case when running on OpenShift. This step patches the existing $NAMESPACE with said label.
• When running on other K8S clusters than OpenShift, this step is not performed.
• Can use vanilla kuttl to run test suites against OpenShift
