OPC UA Adapter: support Namespace index change after OPC UA Server restart

AVEVA adapter for OPC UA should support changes in the Namespace index that can happen after an OPC UA Server service restart.

Currently, if the Namespace index of the source signals change, the adapter stops receiving data for every point in that Namespace. The only way to fix this is reconfiguring manually the data selection, editing the Namespace part of the "nodeId" for each item.

The OPC UA adapter should be able to get the updated namespace indexes from the namespace table in the OPC UA server, without having to edit manually the configuration.

    Thank you for your feedback. I'd like to better understand in what scenarios you'd expect the Namespace index to change. AVEVA Adapters are simple data collection products where it looks for either predefined information (ie. Data Selection configuration) or stream information based on Discovery output, in order to relay data to the appropriate data endpoint(s). At the moment, we don't expect to apply refined logic in the adapter to be able to detect when NodeIds change, but it would be good to understand your exact scenario.
