Expanded Node ID for OPCUA

[danielpeintner]

During a PlugFest we discovered that the opcua binding did not manage to properly resolve expanded node ids

We tried to use

"opcua:nodeId": "nsu=xxxxxx;s=\"LED\".\"State\""

(Note: xxxx was the actual namespace)

instead of something like this

"opcua:nodeId": "ns=3;s=\"LED\".\"State\""

Anyhow, it did not work, and we were not exactly sure whether it is not properly implemented or we are doing something wrong.

@erossignon maybe you have some idea?

I can take this on board. The feature exists in newer versions of node-opcua and need to be called appropriatly in the binding.
