Subnet information is only really needed when the specified `vpc_id` is
not the default VPC for the region where the builder is being executed.
This change uses the AWS API to determine if the VPC provided is a
non-default VPC and only validates the existence of a `subnet_id` if a
user has provided a non-default `vpc_id`.
