Stop using SelfLink

[alewitt2]

Describe the bug
Stop using selfLink: selfLink is being deprecated around 1.20/1.21. we will need to either transition to creating the selfLink for the uses that we need it, or switching to a different attribute. I know selfLink is used in watch-keeper and composite-controller, need to see if it used anywhere else (maybe kube-class). see issue
