Check apps/v1 StatefulSet available before starting its controller

**What this PR does / why we need it**: StatefulSet controller was bumped to use `apps/v1.StatefulSet` already. Without this change, StatefulSet controller will continue to work, but will be broken when `apps/v1beta2.StatefulSet` is removed or disabled. 

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #

**Special notes for your reviewer**:
