The procedure framework is an interface that provides unified state management for those with multiple operations. Ensure consistency by rolling back and retrying. It can be used to deal with fault scenarios. 1. A readme and an example will be written for other developers to use. 2. At that time, it was considered that the procedure could run in a separate process, so it was placed in a separate module. After discussion, the procedure is run in the config node process and will be combined in the next pr. pull/5811。

But I still have some questions about the module, and want to have a discussion: 1. what is it for? (can someone use several sentences or several paragraphs to introduce it? and put the introduction into a README.md file?) . (and I can find 11 kinds of implementations ... why..) 2. why the procedure should be considered as a new "module" rather than just a class "packet"?
