SchedulerService is a wrapper class around the APScheduler library. It is resonpseible for interacting with the scheduler

and scheduling events. This includes the interval events that are registered in the SchedulerRegistry as well as cron events

that are used for sending webhooks. In most cases, unless the the schedule is dynamic, events should be registered with the
|
|
SchedulerRegistry. See app.py for examples.
