场景：
有一系列Job类型的任务需要提交到Kubernetes去运行,这些任务有如下特点：

每个任务拥有独立的Resource Request(CPU and Memory)。
每个任务的执行时间可以认为是和占用资源线性相关的（可配置的公式）。
每个任务会配有最迟的启动时间（一个或多个）。
所有的任务每天至少被调用一次。

需求：
如何基于kubernetes集群去调度这些Job？

k8s里有个CronJob, 但不清楚是否支持limitRange

@xiaoping378 CronJob并不能完全满足需求，详见issue: kubernetes/kubernetes#39411

@Yancey1989 可以用TPR自己实现，官文上有例子
