[OE-core] [PATCH 2/5] oeqa/core/runner: write testresult to json files

[Yeoh Ee Peng]

As part of the solution to replace Testopia to store testresult,
OEQA need to output testresult into json file, where these json
testresult file will be stored in git repository by the future
test-case-management tools.

Both the testresult (eg. PASSED, FAILED, ERROR) and  the test log
(eg. message from unit test assertion) will be created for storing.

Also the library class inside this patch will be reused by the future
test-case-management tools to write json testresult for manual test
case executed.
