We want to test:
if quota <= 0 {as we did for the memory. Otherwise, in case quota == 0, we are gonna end up with resources.VCPUs = 0 because (period -1) / period will return 0.

Right. I also will check period is not zero.
We should run VM(container) regarding OCI spec config.json cpu quota and period. The number of VM VCPUs is defined by quota/period (round up to 1). Signed-off-by: WANG Chao <chao.wang@ucloud.cn>
