Epic Goal

As outlined in the OpenShift enhancement https://github.com/openshift/enhancements/pull/867, The Node Tuning Operator and Performance Addon Operator are getting merged into a single operator running as a core OpenShift component. The CNF team is working on refactoring NTO to use controller-runtime as described by https://issues.redhat.com/browse/CNF-2448 and https://issues.redhat.com/browse/CNF-3431. The PSAP team needs to support this effort in the following ways:

- Code reviews and support (possibly even pair-programming) with the PAO team.
- Expand the e2e test coverage (e.g. Tuned spec.ManagementState) to catch issues with the controller-runtime NTO rewrite.
- Prepare tests to assess the impact of the NTO/PAO merge on CPU/Memory/API server/…

Why is this important?

The NTO rewrite to use controller-runtime is a huge undertaking that needs to be well supported from the PSAP team side. Otherwise we risk regressions not only in terms of bugs, but also operator performance impact.
