Schedule restriction - Add support for start_day_of_week

[heimweh]

Hi,

this adds support for start_day_of_week.
Without start_day_of_week set, a restriction with type weekly_restriction will fail with:

Failed call API endpoint. HTTP response code: 400. Error: &{2001 Invalid Input Provided [Start day of week must be in 1, 2, 3, 4, 5, 6, 7, 1, 2, 3, 4, 5, 6, or 7.]}

Hi @ranjib. Would you be able to take a look at this one? 🙂 Not sure if I missed something.

Bump; would love to see this make it into Terraform (and made available to other users of the library).

@ranjib I would also like to see this merged to use this via terraform :)

Interestingly the field is missing in the online docs as well:

Thank you for this, and very sorry for the delay.

Also thanks for pointing out that this option is missing in the docs @paultyng we have filed an internal ticket to get that fixed up
