Decouple the event type and the scheduled rebalance cache refresh option. (#638)

The previous design is that both on-demand and periodic rebalance scheduling task will request for a cache refresh. This won't be always true moving forward.
For example, the WAGED rebalancer async baseline calculating requests for a scheduled rebalance. But cache refresh won't be necessary.
