thingsboard IoT gateway OPC-UA connector configuration

Starting with version 3.1 of Gateway, we have added a new OPC-UA connector based on the AsyncIO library. Please note that this connector is currently in early testing and may contain some bugs. Therefore, its use in production environments is currently not recommended. To enable it, use connector type "opcua_asyncio".

This guide will help you get familiar with OPC-UA connector configuration for ThingsBoard IoT Gateway. Use a common configuration to enable this extended functionality. We describe connector configuration files below.
