Add support for statefulset spreading to the scheduler

**What this PR does / why we need it**:
The scheduler SelectorSpread priority funtion didn't have the code to spread pods of StatefulSets. This PR adds StatefulSets to the list of controllers that SelectorSpread supports.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #41513

**Special notes for your reviewer**:

**Release note**:

```release-note
Add the support to the scheduler for spreading pods of StatefulSets.
```
