you can introduce one more method without 'retain' argument and pass
'retain' object received in constructor.

> MQTT is a lightweight publish/subscribe protocol frequently used in IoT
> applications.
> Further information can be found at http://mqtt.org
> Initial features include:
> * Full MQTT support (e.g. last will, QoS 0-2, retain, etc.)
> * Spout implementation(s) for subscribing to MQTT topics
> * A bolt implementation for publishing MQTT messages
> * A trident function implementation for publishing MQTT messages
> * Authentication and TLS/SSL support
> * User-defined "mappers" for converting MQTT messages to tuples (subscribers)
> * User-defined "mappers" for converting tuples to MQTT messages (publishers)
