 * Injection qualifier that can be used to inject an {@link java.util.concurrent.ExecutorService}
 * instance used by Jersey client runtime to execute {@link jakarta.ws.rs.client.Invocation.Builder#async() asynchronous}
 * client requests.

 * The asynchronous client request executor service instance injected using this injection qualifier can be customized
