crictl images should list all image tags.

[Random-Liu]

Currently we are listing image by id, and only include the first repo tag.

We should organize the information better.

Docker lists all image tags even they have the same id.

Do It only need to show more? After all crictl already have all image info by client.ListImages.

$ docker images

@yanxuean Actually I tried yesterday, docker images doesn't seem to list image pulled by repo digest. Could you verify?

like this ？

Is this docker images output? I don't remember there is <none>.

[yanxuean]

ok, i will try it. The example as above is from the docker 's office document.
