[Eval] Test suite run annotations

It might be useful to annotate specific test suite runs (at startup, or after the fact) with some additional information, e.g. what changed in the target application (version, configuration properites, prompts, etc.).
Such information should be stored in EF and be queried alongside run details.

No files, tests, or entry points are named. Start by tracing how test suite runs and run details are stored and queried; the work is done when annotations such as application version, configuration properties, and prompts can be attached at startup or afterward, persisted in the evaluation framework, and returned with run details.
