openhab-addons: [mqtt] Errors in the log file after MQTT binding installation

Hi guys! (@davidgraeff)

I’m trying the latest openHAB 2.5.0 SNAPSHOT version and I have found the following errors after installing the MQTT binding:

2019-03-26 15:34:17.609 [ERROR] [org.openhab.binding.mqtt.generic    ] - bundle org.openhab.binding.mqtt.generic:2.5.0.201903260114 (223)[org.openhab.binding.mqtt.MqttChannelStateDescriptionProvider(215)] : Could not load implementation object class org.openhab.binding.mqtt.MqttChannelStateDescriptionProvider
java.lang.ClassNotFoundException: org.openhab.binding.mqtt.MqttChannelStateDescriptionProvider cannot be found by org.openhab.binding.mqtt.generic_2.5.0.201903260114

Many thanks for your work and support!

@bodiroga It doesn’t hurt to have them in different packages. Can you prepare a PR?

Done: #5259! 👍

With build 1564 (built on 31.3.2018) and the jars above I am getting

2019-04-02 18:17:14.623 [ERROR] [org.openhab.binding.mqtt.homie      ] - FrameworkEvent ERROR - org.openhab.binding.mqtt.homie

Downloading the jars mentioned above helps reading data from my broker, but publishing does not work…
