fix: register a destroy hook when the application event trigger

if we register a destroy hook for RemoteConfigFileRepo on the class instance , the static thread pool may be terminated by the bootstrap context closing ,Therefore,it's better to register the destroy hook when the  application is prepared, or when the application fails to start, in order to properly destroy resources
