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

The json testresult file will store more than one set of results,
where each set of results was uniquely identified by the result_id.
The result_id would be like "runtime-qemux86-core-image-sato", where
it was a runtime test with target machine equal to qemux86 and running
on core-image-sato image. The json testresult file will only store
the latest test content for a given result_id. The json testresult
file contains the configuration (eg. COMMIT, BRANCH, MACHINE, IMAGE),
result (eg. PASSED, FAILED, ERROR), test log, and result_id.

Based on the destination json testresult file directory provided,
it could have multiple instances of bitbake trying to write json
testresult to a single testresult file, using locking a lockfile
alongside the results file directory to prevent races.

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.
