// name from the service registry and a subset name. The order of inference
// is as follows:
//
// 1. Service registry lookup. The entire name is looked up in the service
// registry. If the lookup succeeds, the search terminates. The requests
// will be routed to any instance of the service in the mesh. When the
// service name consists of a single word, the FQDN will be constructed in
// a platform specific manner. For example, in Kubernetes, the namespace
// associated with the routing rule will be used to identify the service as
// <servicename>.<rulenamespace>. However, if the service name contains
// multiple words separated by a dot (e.g., reviews.prod), the name in its
// entirety would be looked up in the service registry.
//
// 2. Runtime DNS lookup by the proxy. If step 1 fails, and the name is not
// an IP address, it will be considered as a DNS name that is not in the
// service registry (e.g., wikipedia.org). The sidecar/gateway will resolve
// the DNS and load balance requests appropriately. See Envoy's strict_dns
