主题端支持使用表达式方言获取登录状态和判断权限，例如：
获取当前登录用户名
```html
<div th:text="${#authentication.name}">
The value of the "name" property of the authentication object should appear here.
</div>
```
关于判断登录状态我们并不推荐调用表达式 `${#authentication.isAuthenticated()}`，因为始终返回 `true`，使用以下几种属性表达式代替：
```html
<div sec:authorize="isAuthenticated()">
如果不是匿名用户你会看到我
</div>
<div sec:authorize="isFullyAuthenticated()">
如果不是匿名用户且不是 rememberMe 你会看到我
</div>
```
其他
```html
<div sec:authorize="isAnonymous()">
如果是匿名用户你会看到我
</div>
```
```html
<div sec:authorize="isRememberMe()">
如果是 rememberMe 你会看到我
</div>
```

Console 端判断是否登录需要改一下，目前所有未登录状态都属于一个叫 anonymousUser 的用户

#### 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- [x] Delete documents when posts are unpublished or deleted.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 https://github.com/halo-dev/halo/pull/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 ''
```
