Configure ThreadLoop to be daemon

[eskildsf]

Configuring a sync Client object and connecting it to an OPC-UA host will cause the calling script to hang on exit if disconnect() is not called. By setting the ThreadLoop to be a daemon resolves this issue.

Is it safe?
not correctly closing things is often a very bad ideas. But maybe in that particular case it is worth it... not sure

Hi @oroulet

I don't think I can say "yes" confidently. You probably have a better basis to make that call.

I will say though that it is quite useful for the Python session not to hang if you have an exception which causes a crash. That is probably the most relevant usecase since I do agree that in the best of all worlds the programmer would make the call to disconnect deliberately.
