Use CollisionCount for collision avoidance in StatefulSet controller

**What this PR does / why we need it**:
This PR uses the newly added `CollisionCount` in `StatefulSetStatus` for name collision avoidance when the `StatefulSet` controller creates `ControllerRevision`s. The `CreateControllerRevision` method of the `ControllerHistory` interface was augmented to use a user-specified `collisionCount` instead of the internal probe that always starts with 0. The `StatefulSet` controller uses the `CreateControllerRevision` to create `ControllerRevision`s and when it calls it, it passes in the `CollisionCount` of the `StatefulSet` it manipulates.
