Creating a VPN Connection Monitor

Function

This API is used to create a VPN connection monitor to perform health check between gateways. After a VPN connection monitor is created, the VPN gateway sends probe packets to the customer gateway to collect statistics about the round-trip delay and packet loss rate, thereby monitoring quality of VPN connections between the gateways.
