  - Archive all test case result files

    1. All detailed tempest test cases results are recorded with
       file tempest-report.html rather than tempest.log now.
    2. Archive all results files include functest.log, yardstick.log ...
       for each test case. Otherwise, they will all be in one log file.
    3. Support to set the source files and dest files need to be archived with
       the test case config files rather than hardcode with the source code.
    4. Give the file which used to be parse the results (PASS/FAIL) with the
       test case config files rather than hardcode with the source code.
