All you have to do is return nil here. No use of nil assignment. Also, add unit tests for the same.

Add detailed comment for future reference on this special case:

   // ignore kubeletstats receiver as it holds the field key endpoint, and it
   // is a scraper, we only expose endpoint through k8s service objects for
   // receivers that aren't scrapers.
   case name == "kubeletstats":
	   return nil
