Add `ContainerManager` annotation to created containers
This change adds the following annotation to every container created by podman: ```json "Annotations": { "io.containers.manager": "libpod" } ``` Target of this annotaions is to indicate which project in the containers ecosystem is the major manager of a container when applications share the same storage paths. This way projects can decide if they want to manipulate the container or not. For example, since CRI-O and podman are not using the same container library (libpod), CRI-O can skip podman containers and provide the end user more useful information. A corresponding end-to-end test has been adapted as well. Relates to: https://github.com/cri-o/cri-o/pull/2761 Signed-off-by: Sascha Grunert <sgrunert@suse.com>
