[PATCH v3 11/13] test/telemetry_data: add test cases for character escaping

[Bruce Richardson <bruce.richardson@intel.com>]

Add in some basic unit tests to validate the character escaping being
done on string data values, which tests end-to-end processing of those
values beyond just the json-encoding steps tested by the
"telemetry_json_autotest".
