// MapCloudIP issues a request to map the cloud ip to the destination. The
// destination can be an identifier of any resource capable of receiving a Cloud
// IP, such as a server interface, a load balancer, or a cloud sql instace.
//
// To map a Cloud IP to a server, first lookup the server to get it's interface
// identifier (or use the MapCloudIPtoServer convenience method)
