I can see there is definitely a demand for this plugin. I finally think i got a basic working prototype going (or maybe not). I still have a lot of unit tests to add here, but if anyone wants to give it a try feel free. I'd love feedback.

The instructions can be found on my pull request (#443).

Note: At this time it relies on the paho-mqtt python library. I'm not of fan of using full libraries since the point of Apprise is to make it so you don't need to do this. Perhaps this will just be the first Apprise/MQTT version; eventually we can drop the dependency (we'll see...). There seems to be a lot of overhead with the MQTT protocol (handshaking, multiple supported protocols, SSL, etc). It's kind of nice to just rely on someone who's already ironed out the bugs and at the same time I'm not re-inventing a (rather complicated) wheel. This plugin will gracefully just not work if the dependency isn't installed (but spit an error letting you know why).

I have had some success with my latest set of code and merged it. 👍

Will close this ticket now
