refactor: snapshot attributes and post publish (halo-dev#2709)

#### What type of PR is this?
/kind improvement
/area core
/milestone 2.0
 
#### What this PR does / why we need it:
1. 简化 Snapshot 的指责，去除 Snapshot 中关于 version，publishTime 等与发布相关的东西，Snapshot本身没有发布概念
2. 对应修改文章和自定义页面，将版本的概念转移到拥有 Snapshot 的模型上，如 Post 和 SinglePage

⚠️此 PR 为破坏性更新，对旧数据不兼容，可能导致旧数据文章内容无法显示问题

Console 端需要做出一些修改：
- 将文章发布前调用保存内容的 API 修改为 `/posts/{name}/content`
- 将自定义页面发布前调用保存内容的 API 修改为 `/singlepages/{name}/content`

发布接口提供了一个 `async` 参数，默认值为 `false`此时发布API需要等待发布成功后才返回结果，如果等待超时则提示`Publishing wait timeout.`, 如果传递 `async=true` 表示异步发布，更新完数据就成功，reconciler 在后台慢慢执行。

#### Special notes for your reviewer:
how to test it?
1. 新创建一篇文章，测试点击保存是否成功
2. 新创建一篇文章，测试编辑内容后直接发布是否成功
3. 测试发布过的文章的取消发布状态是否显示未发布状态
4. 对于 Snapshot，新建文章点保存会创建一个snapshot，点击发布则是更新之前点保存创建的一条，所以记录数不会多，发布之后进入编辑随便写点内容直接点发布后查询snapshot则会多一条记录。
5. 文章的 status 里的 conditions 最新添加的都在第一个即头插入，如果连续两次发布则不会在增加 condition，长度超过20条会把旧的 condition 删除掉
6. 自定义页面上同

Implement full-text search of posts with Lucene default (halo-dev#2675)

#### What type of PR is this?

/kind feature
/area core
/milestone 2.0

#### What this PR does / why we need it:

This PR mainly implement full-text search of posts and provide extension point for other search engine.

Meanwhile, I implement ExtensionGetter to get implemention(s) of extension point from system ConfigMap.

But there still are something to do here:

- [x] Udpate documents when posts are published or posts are becoming unpublic.
- [x] Delete documents when posts are unpublished or deleted.

Because I'm waiting for halo-dev#2659 got merged.

I create two endpoints:

1. For full-text search of post

    ```bash
    curl -X 'GET' \
      'http://localhost:8090/apis/api.halo.run/v1alpha1/indices/post?keyword=halo&limit=10000&highlightPreTag=%3CB%3E&highlightPostTag=%3C%2FB%3E' \
      -H 'accept: */*'
    ```

1. For refreshing indices

    ```bash
    curl -X 'POST' \
      'http://localhost:8090/apis/api.console.halo.run/v1alpha1/indices/post' \
      -H 'accept: */*' \
      -d ''
    ```

docs: remove changelog documentation (halo-dev#2540)

#### What type of PR is this?

/kind documentation

#### What this PR does / why we need it:

目前 Halo 处于多版本同时并存发行的现状，所以在各个分支（main、release-1.5、release-1.6）维护 CHANGELOG.md 会变得比较麻烦。所以考虑移除掉仓库内的 CHANGELOG.md 文件，后续以 [releases](https://github.com/halo-dev/halo/releases) 页面提供。
