1. Proposed title of this feature request:

Looking forward to retrieve back last n(3) number of  unused machineconfigs.

2. What is the nature and description of the request?
Extension of the functionality of the oc adm prune renderedmachineconfigs tool to delete all unused renderedmachineconfigs except the last x ones

3. Why does the customer need this? (List the business requirements here)
Better for automation: With this option I could implement an easy automation like e.g. a cronjob. With the actual possibilities I've to create a workaround which first check the amount of unudes renderedmachineconfigs, filter this with there date and then decide which the last x and delete the rest.

4. List any affected packages or components.
