[bug report] /images/json API isn't compatible with Moby

[allencloud]

Issue Description
In the existing API of Pouch, /images/json API isn't compatible with Moby.
File https://github.com/alibaba/pouch/blob/master/apis/types/image_info.go is redundant, and should use https://github.com/alibaba/pouch/blob/master/apis/types/image_summary.go.

Pouch used containerd 1.0.0, and image details are from containerd side. https://github.com/alibaba/pouch/blob/master/apis/types/image_info.go is for containerd, while I think we need to transform that into Moby's API.

Discussed with @Ace-Tang offline, this needs updated. Maybe we can refer to moby/moby#34895, since this PR merged containerd 1.0.0 with moby.
