[FEATURE REQUEST] Set TTL on scheduler_history key

Is your feature request related to a problem? Please describe. If the process is kill -9, or if for whatever reasons Scheduler.Shutdown() fails to execute,
or if RDB.ClearSchedulerHistory() failed, the SchedulerHistoryKey will stay in redis forever.

Describe the solution you'd like Set TTL on SchedulerHistoryKey key, like 3 months?
