    Fix xml request doesn't work with unicode

    Fix bug 1160704

    * httplib2 doesn't work with unicode url and params. So encode all unicode
    to utf-8 before request.
    * Fix xml serializer doesn't work with unicode
    * Decode command argument to unicode in main function
    * Exception's message maybe include unicode, decode message to unicode
    before logging or print.
    * Sync the changing of serializer/deserilizer's code with quantum server code
