Not sure Now() belongs in the interface. Adding a k8s.io/utils/clock.Clock to the cri stats provider seems better.

Thank you @jsturtevant for adding this. I wanted to point out the KEP that me and @haircommander are working on to move all of the stats from pod / container stats from the kubelet to the underlying container runtime (this includes network stats). So long term, it would be great to get these stats implemented directly in containerd CRI API (and get support on windows!). Happy to chat more about this offline, will ping you on slack :)
