Added QoS and retain to the configuration settings of OTDT
While in an Action using the publish method of the MQTT library enables to set QoS and retain, it is better to have default settings where OTDT itself add these settings.
The response to a Trigger could now be left in/done by OTDT - like it should be and was always planned - where it controls the settings of each reply (publish if using MQTT) accordingly.
This again let settings be configured for the appropriate Trigger (response) and therefore the Action be reduced to what they are originally intended to without too much knowing about the current active Trigger.
