Add image info to the verbose status command

[afbjorklund]

Do a combination of the cri-o format (with "labels") and the
containerd format (without "chainID") for the info JSON field.

cri-o
https://github.com/cri-o/cri-o/blob/main/server/image_status.go

        struct {
                Labels    map[string]string `json:"labels,omitempty"`
                ImageSpec *specs.Image      `json:"imageSpec"`
        }

containerd (cri plugin)
https://github.com/containerd/containerd/blob/main/pkg/cri/server/image_status.go

struct {
        ChainID   string          `json:"chainID"`
        ImageSpec imagespec.Image `json:"imageSpec"`
}

The info is supposed to include the history, so make a special
call for that in verbose and reverse order to match containerd.
