Contributor guide

Research direction
Implement a local cache layer for service discovery in Dubbo so that when the registry is unavailable, previously discovered providers are used. Modify RegistryProtocol or ServiceDiscovery to cache instances in memory or a file, and add configuration for cache expiry and refresh.
