重构访问量统计逻辑
1. 去掉了访问量总数存储在 Meter Counter 中的逻辑，因为迁移时是直接像 Counter 自定义模型创建数据，而文章被访问时是存储在 Meter Counter 后定时同步到数据库，这就存在双向同步问题且都有新数据无法知道该如何合并数据。
2. 目前访问时会发送一个事件，当得到事件后会缓存在队列中，每隔一分钟将增量更新到数据库中
3. 评论统计也去掉了 Meter Counter 改为事件队列处理
4. 如果后续要暴露 Metrics 应该使用 Gauge 监控 Counter 自定义模型
5. Counter 自定义模型的查询优化后续可以使用 Indexer 或者加缓存来实现而非将 Meter Counter 当作缓存

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

2. 先通过 `POST /apis/console.halo.run/v1alpha1/posts` 创建一篇草稿（`spec.publish=false`），在获取它并设置 `spec.publish=true` ，更新后期望文章为发布状态 `spec.headSnapshot`, `spec.releasedSnapshot` 都不等于空且等于 `spec.baseSnapshot`)，且 `spec.version=1`（此过程相当于先保存后发布且之前从未发布过）

2. 创建几篇文章、标签、分类、自定义页面
3. console 端能看到访问路径自动带上了 external url 并且通过访问路径能正确访问到相应资源

1. 创建一个层级结构菜单，比如
```
A
|-B
|-C
```
2. 删除菜单 C 然后访问主题端首页不会发生以下异常信息
```
Caused by: java.lang.NullPointerException: Cannot invoke "run.halo.app.theme.finders.vo.MenuItemVo.setParentName(String)" because "childNode" is null

1. 创建文章
2. 由于没有发布，此时访问文章的 permalink 访问不到
3. 发布文章，可以正常访问
4. 更新文章的 `spec.deleted=true`,在访问文章期望404，并且 `metadata.labels` 中的数据正确
5. 自定义页面亦如是

支持通过文章名称获取上一篇和下一篇文章数据
本 PR 通过实现一个固定大小的滑动窗口数据结构来通过传入的文章名称获取上一篇和下一篇文章
例如当具有一系列文章名为 [a, b, c, d, e, f, g]
查询文章名为 d 的文章的上一篇和下一篇则使用一个固定大小为 3 的滑动窗口, 示意图如下
<img width="526" alt="image" src="https://user-images.githubusercontent.com/38999863/198243133-20f77431-1107-4526-9f4f-6a11c68204e7.png">
通过窗口右移来调整当窗口圈住所需元素 D 时且 元素 D 的位置不是窗口的最后一个元素时得到一个想要的窗口
此时：
1. 如果 D 位于 window 中的第一个元素则 D 没有上一篇
2. 如果 D 位于 window 中间则 window 的第一个元素为 D 的上一篇，最后一个元素为下一篇
3. 如果 D 位于 window 的最后一个位置，则 D 没有下一篇

1. 创建几篇文章然后发布
4. 能通过 `${postFinder.cursor(your-post-name)}` 来获取到带有上一页下一页的文章数据
5. 当文章处于第一条时没有上一页，当文章处于最后一页时没有下一页（可以通过`${postCursor.hasPrevious()}` 和 `${postCursor.hasNext()}` 判断按钮是否展示）

#### What this PR does / why we need it:
ReverseProxyRouterFunctionRegistry 的注册方法之前使用了一个 LinkedMultiValueMap<String, String>，相当于是一个 Map<String, List<String>>，当插件启动后扫描到 ReverseProxy 资源保存到数据库会触发 ReverseProxyReconciler 调用`ReverseProxyRouterFunctionRegistry#register`，如果此时插件的 PluginApplicationContext 还没有被创建好，register 时会在中途因为获取不到 PluginApplicationContext 而失败然后 requeue，而 LinkedMultiValueMap 此时已经保存了一条记录 requeue后再执行 LinkedMultiValueMap（即`Map<String, List<String>>`） 这个 value 是一个 List 需要更多的判断来防止重复，需要用一个 Map<String, Set<String>>这样的结构来保证 requeue 时 ReverseProxyRouterFunctionRegistry 中集合结构之前的数据一致性这样更方便，所以将从 spring 的 LinkedMultiValueMap 切换到 guava 提供的 LinkedHashMultimap（它的结构是Map<K, Set<V>）

渲染模板页面时将被渲染的模板名称填充到试图模型中作为 templateId
为什么需要它：
1. thymeleaf 渲染模板可以使用 fragment，此时在 thymeleaf 的 IElementTagProcessor 等处理器中获取到的 template name不一定是例如 post.html这样的名称
2. 比如渲染文章模板 post.html 而 #2569 计划将要在 theme.yaml 中通过配置允许用户选择文章所渲染的模板，因为无法确定渲染模板的标志，例如有些处理器想在文章页插入 head 这样的需求就需要知道哪个模板是文章页。see also [issuecomment-1215135195](https://github.com/halo-dev/halo/issues/2322#issuecomment-1215135195)
所以目前想到的是通过在 render 时填充一个 templateId 到 view model 中标识模板身份
