Description

The following classes extends CapacitySchedulerTestBase, but it is unnecessary. 

 - TestCapacitySchedulerMultiNodes

 - TestCapacitySchedulerMultiNodesWithPreemption

 - TestCapacitySchedulerSchedulingRequestUpdate

 - TestCapacitySchedulerWorkflowPriorityMapping

The helper methods could be static, so inheritance is not needed here.

 

Later the TestCapacityScheduler can be split by features, where the CapacitySchedulerTestBase will come handy.
