Multi OPC Server and auto-reconnect

[Maddin-619]

For my use case I need to log data form diffrent opc ua server so I made a few changes that you can config multiple opc ua endpoints with their datapoints you want to log in the config file.

When a opc ua server restarts the connection should be reestablished automatically with all the monitored itmes. The opc ua npm package unfortunately dosen't do that. I tested with python-opcua Server. The solution is a little bit hacky: When the opc ua server comes back up the client object gets newly initialized.

Reconnection no work for me.
Freeze in this message:

Can you give me more information. Which server? Is it freezing when loosing connection or when Server is up again?
This reconnect mechanism listens on the event when server gets back up and than initializes new client connection.
I will check it tomorrow. Maybe there is now a better solution provided by the opc ua stack. Last year there was no way to get the monitored items automaticly reconnecting.
