Comment 8 for bug 1558812

So, my question here is why approach it from the perspective of creating the subnetpool then going through and updating all subnets with the subnetpool_id. Would it be simpler to perform this update for the user when the subnetpool is created?

We know that the subnets can't already overlap, so why not detect what subnets fall into the subnetpool prefix range and automatically update the subnet's subnetpool_id? These seems like a simpler approach rather than adjust the current subnets resource.
