Creates an event.
If you provide recurrenceRule, an event with {"recurrenceType": "MASTER"} is created. Then, you can't set start.localDate to a past date, though the time can be earlier on the same day. You can, however, create single-occurrence events for past dates.
You can't create an event with recurrenceType set to INSTANCE or EXCEPTION. INSTANCE events are generated automatically based on the recurrence rule in the relevant MASTER event. EXCEPTION events are automatically created when you update an INSTANCE event, which changes its recurrenceType to EXCEPTION.
