I donot know why

k8s:1.17.3
volcano:v1.0.1
volcano-deviceplugin:1.0.0
docker:18.06.3-ce
os : ubuntu18.04
arm : x86

Refer the GPU share user doc (https://github.com/volcano-sh/volcano/blob/master/docs/user-guide/how_to_use_gpu_sharing.md).
Currently, only support specify GPU share memory, to specify GPU number is a limitation. We are planning a project to handle this case.
