[Le Yao]

PR link: https://github.com/kubevirt/kubevirt/pull/2980

Intel QAT can offload some of the workloads like cryptography and compression from the CPU to hardware. And kubernetes container already can utlize the QAT PCI-device through QAT device plugin, so I want to enable it in Kubevirt VM in Kubernetes cluster to accelerate applications running in VM.

I would like to get advices from you to complete the PR process.

Thanks.
