// Creates a VPN connection between an existing virtual private gateway or transit
// gateway and a customer gateway. The supported connection type is ipsec.1 . The
// response includes information that you need to give to your network
// administrator to configure your customer gateway. We strongly recommend that you
// use HTTPS when calling this operation because the response contains sensitive
// cryptographic information for configuring your customer gateway device. If you
// decide to shut down your VPN connection for any reason and later create a new
// VPN connection, you must reconfigure your customer gateway with the new
// information returned from this call. This is an idempotent operation. If you
// perform the operation more than once, Amazon EC2 doesn't return an error. For
// more information, see Amazon Web Services Site-to-Site VPN (https://docs.aws.amazon.com/vpn/latest/s2svpn/VPC_VPN.html)
// in the Amazon Web Services Site-to-Site VPN User Guide.
