Review comment:
       Yep, this's a good question, there were some related use case of Spark with volcano in production can be shared in here:
   - Case1 (this PR): `minCPU` = specified `minCPU`: for users who know their own cluster resources well, this is the basic user case.
   - Case2: `minCPU` = driver.request + `executor.number` * `executor.request`: for users who don't care much about job resource usage.
   - Case3: `minCPU` = (driver.request + `executor.number` * `executor.request`) * `factor`, for users want to guarantee the resources of the job in some level, but also want to improve the utilization of the cluster.
