reactor&remove: 重构applications模块 & 移除applications、perms中已不再使用的模块 (#5374)

* reactor: 重构applications模块 & 删除applications、perms中已不再使用的模块

 * reactor: 1. 针对application.attrs字段的view-serializer映射逻辑，采用DynamicMapping的方案重写;
 * reactor: 2. 删除applications和perms模块中已不再使用的database-app/k8s-app/remote-app模块;

* reactor: 添加迁移文件(删除perms/databaseperrmission/remoteapppermission/k8sapppermission)

* reactor: 修改细节
