IsPodCPUUnbounded returns true if the cpu use is unbounded for any container in pod.
IsPodMemoryUnbounded returns true if the memory use is unbounded for any container in pod.
NewResourceQuotaManager creates a new ResourceQuotaManager.
PodCPU computes total cpu usage of a pod.
PodMemory computes the memory usage of a pod.
