Add 'remove-slow-upload-seeds' to 'action' keyword in order to remove torrents with slower upload speed.
添加'remove-slow-upload-seeds'到'action'关键字, 从而能够删除慢速上传的种子.

Example:

mytask:
  ...

  ...
  ...
  strategies:
    limit_max_torrents:
      status:
        - downloading
      maximum_number:
        limit: 30
        action: remove-slow-upload-seeds
  delete_data: true

感谢你的PR，很有用的功能，可以合并。不过在合并之前，我想请你再补充一些代码：

1. 单元测试。请在 pytest/test_strategies/cases/ 目录下的 free_space、maximum_number、remote_free_space、seed_size 目录中补充单元测试代码，以测试功能是否正确。
2. 与之对应，是否需要有 remove-fast-upload-seeds，以满足部分用户的需求？

感谢反馈，会跟进相关内容，估计要到本周末。

问一下，因为之前没用过pytest，reference data那里也要准备吗? 看了一下cases里面有提到 - Torrent - 数字，这里应该是指reference data里面的种子名对吧?

不用，种子的测试数据已经准备好了，只需根据测试数据找出会删除的种子即可。另外在这里我有个小失误，测试数据其实是在 data.json 里，reference_data.py 已经过时了，我没有及时删除。

对的

hi my apologizes.. I have forgot about this PR for quite some time. I have further added remove-fast-upload-seeds, as well as the unit test cases. Everything turns out to be good. Please review.

Thanks for update. In terms of user experiences, I will further create a PR to cover 'remove-fast-download-seeds' and 'remove-slow-download-seeds'. Stay tuned.

新功能
在 action 关键字中添加了 remove-slow-upload-seeds 和 remove-fast-upload-seeds 两个动作。 (#127) 感谢 @vincent906！

I'm afraid there is typo here... 906 --> 806
