List a template's columns
Lists the template's columns, ordered by position, paginated. Validation constraints are not included.
Send the optional X-Customer header (external ID, email or UUID of one of
your customers) to read the columns as that customer: a restricted template
the customer is not granted returns 404, and so does an unknown customer.
