#### What this PR does / why we need it:
使用 SpringComponentsFinder 覆盖 pf4j 默认实现的插件组件类缓存逻辑，以解决插件安装后缓存没有更新导致插件类加载不正确问题
原问题浮现步骤：
1. 先删除插件目录的所有插件
2. 通过接口上传一个插件`apis/api.halo.run/v1alpha1/plugins/install`
3. 启动它
4. 再上传另一个插件并启动它就会发现这个插件无法启动
现在修复过后可以重复测试上述步骤并观察日志显示的插件组件是否被正确加载,再此之前你可能需要配置以下日志级别
```
logging:
level:
org.pf4j.AbstractExtensionFinder: DEBUG
```
启动插件时观察这样的日志是否符合预期：
```
r.h.app.plugin.SpringComponentsFinder : Read 'META-INF/plugin-components.idx'
org.pf4j.AbstractExtensionFinder : Found possible 2 extensions:
org.pf4j.AbstractExtensionFinder : run.halo.template.TemplatePlugin
org.pf4j.AbstractExtensionFinder : run.halo.template.ApplesController
r.h.app.plugin.SpringComponentsFinder : Load [2] component names into storage cache for plugin [PluginTemplate].
```
可以结合此 PR 上传插件进行测试 https://github.com/halo-dev/halo-admin/pull/590
