Default, Current method will be invoked by the ServiceDiscoveryRegistry on the subscription, and it's mandatory to
add the ServiceInstancesChangedListener argument
into EventDispatcher whether the subclass implements same approach or not, thus this method is used to
trigger or adapt the vendor's change notification mechanism typically, like Zookeeper Watcher,
Nacos EventListener. If the registry observes the change, It's suggested that the implementation could invoke
ServiceDiscovery.dispatchServiceInstancesChangedEvent(String) method or variants
