Support CNI network plugin in Frakti

[resouer]

Need to support CNI plugin in Kubernetes + Frakti. The implementation requires finding a way to generate network configuration from CNI and pass these information to hyperd in expected syntax.

A very similar approach is CNI plugin support in CRI-O, please check these for details:

cri-o/cri-o#237
https://github.com/kubernetes-incubator/cri-o#setup-cni-networking

TODOs:

• Basic cni network plugin support Cni integration #62
• Checkpointing network info
• CNI configure examples
• CNI e2e tests
• deployment, e.g. by make install

@YaoZengzeng Would you like to continue those CNI related work?

[YaoZengzeng]

@feiskyer Yes, of course

TIP: we could avoid network interface scanning after containernetworking/cni#145 is merged.

[feiskyer]

All done.

@YaoZengzeng containernetworking/cni#145 is merged, please update the existing code when you have time.
