[test-API PATCH 1/4] add a feature to support the use of xml file by testcases directly

[Guannan Ren <gren@xxxxxxxxxx>]

    src/testcasexml.py: the function will be called just before
    calling main function in testcase. The purpose of it is to
    replace the opition(if present) 'xml = file_path' with
    'xml = xmlstring' and pass it into testcase after replacing
    keywords in the xml file based on the opitional_params in testcase
