Removal of openHAB specific MQTT discovery patch "ohdisc", as it is no longer required with openHAB 4.3 and later, and with openHAB before 4.3 MQTT discovery never was fully implemented anyway.
* [DISC] Add runtime configuration for OpenHAB
Add an MQTT configurable system key "ohdiscovery" for OpenHAB auto discovery
* Docs and environments update
* Add OpenHAB3 tutorial and BLE binary
* Small text changes
Just a few small text changes, also writing out OMG as OpenMQTTGateway, probably clearer for new to OMG users.
