Updating the log level in NROP CR doesn't affect log level of the controller pod of the operator

The log-level Trace comes in handy for debugging when one needs to increase verbosity. However, NROP CR update only updates the log level of the RTE and not the controller pod, although there are logs that need increased verbosity to be shown.

unfortunately we can't solve this easily because we would need to change the command line flags of the operator binary, which are controllerd by the Deployment which are owned by the OLM. The only alternative which comes to mind is to have a override configuration file, but this seems a lot of work for this task

we can add a top-level optional field in NUMAResourcesOperator and change the log level dynamically.

But we need to make sure this works with klog (it should) but also with structured logging, which means with logr.
