Special notes for your reviewer:

how to test it?

• 测试 GET /plugins/{name}/setting 是否能正确获取到插件名称对应的主题的 Setting。
• 测试 GET /plugins/{name}/config 是否能正确获取到插件名称对应的主题的 ConfigMap。
• 测试 PUT /plugins/{name}/config 是否能更新插件的 ConfigMap，如果名称不匹配则抛出异常。 切换用户为其分配主题的查看权限可以有权限调用以上描述的 GET 请求的 endpoints，管理权限可以调用 PUT /plugins/{name}/config。 /cc @halo-dev/sig-halo
