Description of problem

When running with latest Kubernetes, Containerd and Kata, Kata setup as shimv2

Kubernetes v1.14.0 + Containerd 1.2.5 + kata-runtime : 1.6.0

[plugins]
  [plugins.cri]
   [plugins.cri.containerd]
     [plugins.cri.containerd.runtimes.kata]
        runtime_type = "io.containerd.kata.v2"

We get incorrect metrics reported (all metrics reported as 0). This means that scaling is also broken.

Early investigation shows that the metrics are being picked up purely from the container cgroups.
Moving QEMU vCPU threads into container cgroups shows metrics being reported properly.

This means that kubelet is not obtaining the metrics via cri, or that containerd is not obtaining the metrics from the kata-shim.
