Background

目前使用qiankun2.x的版本，业务提出需求在发布新的版本时候，期望可以不刷新页面（主应用暂时不考虑）进行该系统的热重载。类似于pc端的热更新，期望qiankun可以导出unload方法，完全销毁app的生命周期，业务系统再次将其重载。

Proposal

1. 翻看源码发现不能热更新的原因是因为import-html-entry中缓存了 embedHTMLCache
2. qiankun在importEntry时，如果已经获取过html资源，每次获取的都是内存中的html，以至于script & style也是缓存的
3. 我的解决方案是，在import-html-entry中导出根据app去清除缓存的钩子函数
4. 在qiankun中包裹其方法，根据single-spa的appStatus进行卸载应用

Describe the feature you'd like:

It would be nice to update both packages documentation and examples to reflects the newest changes made in this PR #164

Suggested implementation:

Update README.md files along with examples, following the existent ones.

There is a lot of pending documentation here to describe the wonderful features of QCObjects. So a blowing idea came to mi mind. Why not write all the related articles in a selected network like Dev.To and take these contribution articles automatically downloaded and processed to a centralised documentation website?

Dev.To has a simple and incredible REST API to do so, and using the link bell

add ability to provide flag "--w" for watching the file.
