Dynamic MQTT connections (#3189)
* add mqtt-control - adds auto-connect option to broker - add new node mqtt-control - adds i18n messages - adds documentation * documentation tweaks * built in documentation improvements * fix tip layout causing oversized editor * remove unused requires * add missing `unsubscribe` dropdown option - oddly forgotten - now added * ensure clientid is updated dynamically * [rewrite] move mqtt-control login into mqtt-in * Remove dynamic label * remove redundant mqtt-control code left overs * Callback for brokerConn.connect (improve done()) - done is now called on connect callback * fix race condition if connect/disconnect too fast - node.connected and node.client.connected getting out of sync * fix connection fail when switching protocol 3 ~ 5 - ensure protocolId is correct for protocolVersion * change msg.subscribe prop to `msg.topic` * unsub all topics if msg.topic is `true` * delete temprary debugger statements * Final rework of dynamic mqtt connections Co-authored-by: Steve-Mcl <sdmclaughlin@gmail.com>
