MT#63050 /api/customers email_template auto assign

* POST /api/customers now assigns reseller's default email_templates
  that are not specified in the DTO. If reseller's default template
  does not exist (reseller that was created via UI v1 without values),
  it automatically created as a copy of the raw default template
  for the reseller, and then assigned to the customer.
