Implement rollback during create handlers with typescript plugin

Hello,

I'd like to write a custom type using the typescript plugin. The docs talk about [progress chaining](https://docs.aws.amazon.com/cloudformation-cli/latest/userguide/resource-type-develop-stabilize.html) but it's not clear to me exactly how to write a simple plugin that:

1. First calls one AWS service
2. Then calls another AWS service, and if this step fails, retry it, or rollback the first step so that we don't accumulate dangling resources.

从链接的 CloudFormation 文档中关于进度链式处理和资源类型稳定化的部分开始，以了解所请求的行为。将完成定义为：形成一种清晰的 TypeScript 插件方案，用于调用两个 AWS 服务，并重试第二步或回滚第一步创建的资源。
