// Associates a customer gateway with a device and optionally, with a link. If you
// specify a link, it must be associated with the specified device. You can only
// associate customer gateways that are connected to a VPN attachment on a transit
// gateway or core network registered in your global network. When you register a
// transit gateway or core network, customer gateways that are connected to the
// transit gateway are automatically included in the global network. To list
// customer gateways that are connected to a transit gateway, use the
// DescribeVpnConnections (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeVpnConnections.html)
// EC2 API and filter by transit-gateway-id . You cannot associate a customer
// gateway with more than one device and link.
