Python Mqtt and exception cleanup

[jmthomas]

closes #1197

Sorry for the noise in there about the exceptions but I started in on it during MQTT implementation and it all sort of rolled together. I removed the ssl parameter because I don't think it makes sense by itself and only applies if an option is set. That is breaking but this is COSMOS 6 and I think the MQTT usage is pretty low.
