Scheduled Delivery Parameters Exclusivity to Looks

[jenniferpaige]

When trying to update a delivery schedule for a dashboard through the python SDK, the parameters of require_data ,require_no_data, and require_change can be added through the method (and consequently reflected in an API call for that schedule), but ultimately are not employed when the schedules run.

While the API reference guide notes that they can be used with dashboards:
require_results - Delivery should occur if running the dashboard or look returns results
require_no_results - Delivery should occur if the dashboard look does not return results
require_change - Delivery should occur if data have changed since the last run

It seems that those parameters exclusively apply to Looks and cannot be used with dashboards. This is only noted in two places:

1. A sample script on for managing schedules

2. Deep into a single page of Looker documentation

Please update documentation or update the function.
