为 Youki 实现 CRI 接口

[ichAB]

1.编写了简单的 YAML 解析功能以及命令行功能
2.实现了 Pod 的概念，可以利用 Pause 容器处理容器的 Namespace
3.调用Youki Library ，创建、启动、删除Pod，查看Pod的状态

Pull Request Overview

This PR implements the CRI interface for Youki, adding YAML parsing support, a Pod concept using a pause container for namespace handling, and various container lifecycle commands (create, start, kill, delete, state).

• Added new CLI commands for container operations such as kill, start, state, create, and delete.
• Introduced Pod YAML configurations and persistent Pod metadata storage.
• Integrated enhanced root path determination and basic CRI module stubs.

缺少 README.md 介绍如何构建和测试

[genedna]

看起来这个是一个测试文件，你需要一个 tests 的目录来存放测试用的文件。

测试文件的命名需要跟测试的目标一致，从 container_task.yaml container_task1.yaml 是看不出来这个测试任务的内容

[genedna]

这个文件是启动必须的么？

[ichAB]

目前是必须的。
目前启动pause容器需要手动提供pause容器的bundle和config.json文件。

那你在工程里面要有一个目录叫 pause ，里面放对应的内容，不是放在项目的根目录下
