OPCUA response code and details are not reported in PLC response code

[ottlukas]

the attached screenshot shows an OPCUA response code as it is received by the underlying milo client, but the OPCUA driver reports only NOT_FOUND,
it would be great, if the underlying details are included in the OPCUA response code; the real cause for a problem is important for problem solution

This is probably already solved by other commits, however there are some more updates in #1007 which do address handling of UA response codes.

Can this be closed now @hutcheb @splatch ?

Completed via #1007, probably it was improved even earlier through series of fixes we had in 0.11 release.
