How can i add some Parameters (QueryString) to a new Instance?

```auto
Publisher publisher = Publisher.createInstance(vhost, applicationName, appInstanceName);

publisher.publish("myStream", "live");

```

So i can read it with

```auto
Map<String, String> fields = HTTPUtils.splitQueryStr(client.getQueryStr());

```
