Alban Crequy 28e4fb25f4 cri: add annotations for pod name and namespace
cri-o has annotations for pod name, namespace and container name:
https://github.com/containers/podman/blob/master/pkg/annotations/annotations.go

But so far containerd had only the container name.

This patch will be useful for seccomp agents to have a different
behaviour depending on the pod (see runtime-spec PR 1074 and runc PR
2682). This should simplify the code in:
b2d423695d/pkg/kuberesolver/kuberesolver.go (L16-L27)
