Report scheduling

The ​SIA​ Reporting API supports scheduling reports on a recurring basis, either DAILY or WEEKLY.

• If recurrence is set to WEEKLY, you must also set dayOfWeek to one of
  MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, or SUNDAY.
• If recurrence is set to DAILY, omit dayOfWeek from the request and its value remains null.
