controller manager fails to launch new gatekeeper

Followed the Instructions on https://github.com/replicatedhq/gatekeeper#getting-started but the controller manager fails to launch new gatekeeper. controller manager logs show error getting statefulset.

Looking at the code, value hard coded for the controller manager is gatekeeper-controller-manager but the name used for the statefulset in rendered.yaml is controller-manager.

Fixing the statefulset name in rendered.yaml resolves the issue.
