Add Setup Probe for IsIdentifiable / NER daemons / test cases

[tznind]

Background

Setup verb was added to smi in #945 . It checks that required services are accessible (using details in config files) and that microservices are able to boot successfully. It supports both unattended (spectre console results table + zero/nonzero exit code) and interactive (terminal gui).

Enhancement

To prevent regressions in our NLP related features we should also add support for checking that:

• Rules files exist
• NLP daemons are running at the end of any SocketRule

Possible

• Run 'deployment specific' test scripts (detect if environment has misbehaving dependencies or NLP that doesn't classify what we expect)
  • for given input text of A then the following problem data should be detected X,Y
  • might be easier to point this to a script e.g. in Python or something for finer grained asserts / test harness type stuff

[rkm]

The last point may not fit in this feature on second thought. We'll want to run a range of tests, not all via c#, so perhaps that aspect is better handled in a scripting language such as python.

This is tied to the dev/test environment, so this should become clearer as that work progresses
