What is the nature and description of the request?

To increase the debugability of the OpenShift product, the support teams intermittently need to set each component in debug mode to collect additional information when bug-finding.
Performing this with the MachineConfigOperator requires excluding it from the CVO and manually changing the deployment. Many OpenShift components provide this ability through the use of a CR.
There is already an ongoing request for adding `library-go` functions to the MCO but forking this as a separate request to ensure/track the `logLevel` configuration is completed as operators have excluded this option.

Why does the customer need this? (List the business requirements here)

This is requested by the CEE/Support Division of Red Hat to align with the initiative of increasing the debugability of OpenShift.
