LWT should be configurable

[BadWolf42]

Last Will and Testament topic and values should be configurable. Some online Broker only allows RW to some topics, resulting in a crash of the jMQTT Client Broker instance.

[Domochip]

I think we need first to adapt python daemon to not crash for this kind of error. Then maybe get this error back to Jeedom. (cmd = errorReport)

And finally add a broker configuration to use LWT or not

The daemon doesn't crash, the client just receives unexpected disconnection from broker!.

OK, good, option to disable status publish is available by commit : https://github.com/Domochip/jMQTT/commit/86f583311577aa50eec9d53c8dd5c90123817998

[AlexpFr]

I just tested on the AWS cloud, it works well, I was able to subscribe to the topic of my equipment. (in MQTTs of course).

Thank you so much !

[Domochip]

you're welcome ;-)
