Functions
int	azure_iot_hub_init (azure_iot_hub_evt_handler_t event_handler)
	Initialize the module.

int	azure_iot_hub_connect (const struct azure_iot_hub_config *config)
	Establish connection to Azure IoT Hub. The function blocks until a connection to the hub is established on the transport level. Subsequent calls to other library function should await AZURE_IOT_HUB_EVT_CONNECTED and AZURE_IOT_HUB_EVT_READY events.

int	azure_iot_hub_disconnect (void)
	Disconnect from Azure IoT Hub. Calling this function initiates the disconnection procedure, and the event AZURE_IOT_HUB_EVT_DISCONNECTED is received when it is completed.

int	azure_iot_hub_send (const struct azure_iot_hub_msg *const tx_data)
	Send data to Azure IoT Hub.

int	azure_iot_hub_method_respond (struct azure_iot_hub_result *result)
	Send response to a direct method invoked from the cloud.
