[Improvement]: Rename native middleware variable 'SDV_MQTT_ADDRESS' #90
Description
Description
The name is a bit misleading: "MQTT" is a protocol and cannot have an address. The address refers to the message broker.
Suggested Solution
Replace name of the variable by "SDV_MQTTBROKER_ADDRESS" (or maybe "SDV_MQTT_BROKER_ADDRESS" (depending on the possible service names).
Maybe keep old name for a while with deprecation warning if still used.

Additional Context
Needs to be fixed in Python and C++ SDK plus devenv-runtimes.
