Merge pull request #37208 from gmarek/controllers

Automatic merge from submit-queue (batch tested with PRs 37208, 37446, 37420)

Change 'controller.go' filenames to more meaningfull ones

Controller logic should sit in uniquely named file, not `controller.go`, as the latter makes it very hard to understand controller-manager logs.
