Fabiano Fidêncio f33f2d09f7 runtime: image-pull: Make it work with nerdctl 
Our code for handling images being pulled inside the guest relies on a
containerType ("sandbox" or "container") being set as part of the
container annotations, which is done by the CRI Engine being used, and
depending on the used CRI Engine we check for a specfic annotation
related to the image-name, which is then passed to the agent.

However, when running kata-containers without kubernetes, specifically
when using `nerdctl`, none of those annotations are set at all.

One thing that we can do to allow folks to use `nerdctl`, however, is to
take advantage of the `--label` flag, and document on our side that
users must pass `io.kubernetes.cri.image-name=$image_name` as part of
the label.

By doing this, and changing our "fallback" so we can always look for
such annotation, we ensure that nerdctl will work when using the nydus
snapshotter, with kata-containers, to perform image pulling inside the
pod sandbox / guest.
