/**
 * Delete Vpn Gateway Action Sample
 * Deletes a VPN gateway. Use this when you want to delete a VPC and all
 * its associated components because you no longer need them. We recommend
 * that before you delete a VPN gateway, you detach it from the VPC and
 * delete the VPN connection. Note that you don't need to delete the VPN
 * gateway if you just want to delete and re-create the VPN connection
 * between your VPC and data center.
 * AWS might delete any VPN gateway if you leave it inactive for an extended period of time
 * (inactive means that there's no VPN connection in use with the VPN gateway).  
 * @param Amazon_EC2_Interface $service instance of Amazon_EC2_Interface
 * @param mixed $request Amazon_EC2_Model_DeleteVpnGateway or array of parameters
