[dts] [PATCH v2] framework: Adding JSON reporter

[Radoslaw Biernacki <radoslaw.biernacki@linaro.org>]

This patch adds the JSON reporter class which puts the results
into output/test_results.json file
Having JSON file format for results is usefull for CI integration.

v2:
- results from all DUT's and targets are now stored in single JSON file
- "N/A" and "BLOCKED" are also used as test result
