Add a --json flag, which when specified when kunit_tool is run, calls method get_json_result. This is a method within kunit_json.py that formats KUnit results into a dict conforming to the following KernelCI API test_group spec: https://api.kernelci.org/schema-test-group.html#post. The user can specify a filename as the value to json in order to store the JSON results under linux/. Tested within kunit_tool_test.py in a new test case called KUnitJsonTest.
