    Support retuning detailed info of "instance list" command

    Currently, the "instance list" command includes the "image",
    "instance_type", "availability_zone" columns, but they are always empty,
    because the api GET /instances don't return these info, we should use
    GET /instances/detail API to get more detailed info.
