jmeter 创建100个现场组，每个线程组里面有1个http请求，http接口内容为读取CSV文件

思路：先读取csv文件，将数据放到list数组里；再创建线程组和接口并填写数据

        csvLines = Files.lines(filePath)
                       .filter { line -> line.trim() && !line.trim().startsWith("#") }
                       .map { line -> line.trim() }
                       .collect(Collectors.toList())
