Allocate device core usage

Allocate device core to container

Allocate a percentage of device core resources by specify resource nvidia.com/gpucores. Optional, each unit of nvidia.com/gpucores equals to 1% device cores.

      resources:
        limits:
          nvidia.com/gpu: 1 # requesting 1 GPU
          nvidia.com/gpucores: 50 # Each GPU allocates 50% device cores.

NOTICE: HAMi-core uses time-slice to limit device core usage. Therefore, there will be fluctuations when looking at GPU utilization through nvidia-smi
