/**
* Create Subnet Action Sample
* Creates a subnet in an existing VPC. You can create up to 20 subnets in a VPC.
* If you add more than one subnet to a VPC, they're set up in a star topology with
* a logical router in the middle. If you feel you need more than 20 subnets, you can
* request more by going to http://aws.amazon.com/contact-us/vpc-request/.
* When you create each subnet, you provide the VPC ID and the CIDR block you
* want for the subnet. Once you create a subnet, you can't change its CIDR block.
* The subnet's CIDR block can be the same as the VPC's CIDR block (assuming you
* want only a single subnet in the VPC), or a subset of the VPC's CIDR block.
* If you create more than one subnet in a VPC, the subnets' CIDR blocks must not overlap.
* The smallest subnet (and VPC) you can create uses a /28 netmask (16 IP addresses),
* and the largest uses a /18 netmask (16,384 IP addresses).
* Important
* AWS reserves both the first four and the last IP address in each subnet's CIDR block.
* They're not available for use.
* AWS might delete any subnet you create with this operation if you leave it inactive
* for an extended period of time (inactive means that there are no running Amazon EC2
* instances in the subnet).
* @param Amazon_EC2_Interface $service instance of Amazon_EC2_Interface
* @param mixed $request Amazon_EC2_Model_CreateSubnet or array of parameters
