Feat ✨: use tox in test job

Describe Request:

Use tox to run your test suite with the test job - next to unittest and pytest.

Examples:

I would expect the following to work:

- python/test:
   pkg-manager: pip
   test-tool: tox

It would be nice to add another parameter tox-posargs to interactively pass positional arguments to tox.

从 src/jobs/test.yml 开始，比较现有的 unittest 和 pytest 选项是如何接入测试作业的。查看 issue 中链接的 tox 文档，然后验证使用 test-tool: tox 的示例能够正常工作，并且可以按要求传递位置参数。
