问题描述
有许多类似 issue 提到过 429 相关的问题，比如 #121 和 #805，但是并没有从根本上解决问题。
通过 WebDAV 列出目录时整个目录都在一个请求里返回，对应向阿里云盘发出的多个 HTTP 请求，所以客户端无法做 rate limit，只能靠 aliyundrive-webdav 自己限制。然而目前 aliyundrive-webdav 仅进行 3 次重试，且重试间隔极短（如所附日志所示）。另外重试的次数和间隔也均为 hard-coded，无法通过命令行调整：
希望能做出以下改进：
- 添加命令行选项，比如
--retries和--retries-interval - 增加 rate limit 机制，可以尝试这个库，或参考这个 issue
- 识别阿里云盘返回的 header 以调整重试时间
重现步骤
- 启动
aliyundrive-webdav - 用任意 WebDAV 客户端尝试列出一个大目录
