Pass clientset's Interface to CreateScheduler.

**What this PR does / why we need it**:
CreateSchedueler takes clientset.Clientset param and passes it to NewConfigFactory which takes clientset.Interface. It'd be better for CreateSchedueler to take clientset.Interface to be in sync with NewConfigFactory and it would be easier to reuse CreateSchedueler in implementations which relies on interface rather than actual client implementation.
