HelloResource example- webclient should be closed

[fiorenzino]

if i'm right, you should close the webclient after use:

private Single<String> get(Vertx vertx, URI uri) {
    WebClient client = WebClient.create(vertx);
    Single<HttpResponse<Buffer>> responseHandler =
            client.get(uri.getPort(), uri.getHost(), uri.getPath()).rxSend();

    return responseHandler.map(response -> response.body().toString())
            .doAfterTerminate(
                    () -> {
                        client.close();
                    }
            );
}
