[FEATURE REQUEST] Custom ticker value for heartbeater duration

[RiskyFeryansyahP]

Is your feature request related to a problem? Please describe.
Currently, in our production environment, I have 9,000 scheduled entries that run once every week and once every month. However, I've noticed that the CPU utilization on my Redis spikes continuously. You can see this in the image below.

When I investigated the reason for these CPU spikes, I disabled the scheduler in asynq, and the CPU usage returned to normal. While examining the code for the scheduler in asynq, I found that the heartbeater inside asynq runs every 5 seconds (hardcoded) using a ticker. This process involves scanning through cron entries and performing WriteSchedulerEntries.

Describe the solution you'd like
I have an idea to configure the ticker duration based on SchedulerOpts. This way, the ticker duration is not hardcoded and can be defined through configuration when initializing NewPeriodicTaskManager.
