What this PR does / why we need it:

Up until now the container information were populated only through the cri api. There are cases in which this is not sufficient (e.g. bottlerocket): for example the containerd runtime keeps the containers creates through the cri api separated from the ones created with the containerd api. This PR aims to support also the containers created with the vanilla containerd api.

Which issue(s) this PR fixes:
