/**
* 调度任务注册器基类
*
* 实例化时需要实现fetchConfigs方法，用于获取调度任务配置，返回值类型为基于`ECronTaskService`的数组
*
* 注意莫要遗忘 `@Task.Register` 装饰器，否则不会被扫描到
*
* @example
* ```typescript
* @Task.Register
* class CronTaskRegister extends ICronTaskRegister {
* override async fetchConfigs(): Promise<ECronTaskService[]> {
* const taskConfig = new ECronTaskService();
* taskConfig.Id = 1;
* // 基于class属性动态加载对应的调度任务服务类
* taskConfig.class = 'TaskService';
* taskConfig.title = '测试任务';
* taskConfig.description = '测试任务描述';
* taskConfig.cron = '*\/5 * * * * *';
* return [taskConfig];
* }
* }
* ```
