status: granular output for directories

Imagine dvc tracking a directory full of images and files containing labels.

If I delete/change/update a label or image, dvc will tell me that something in the directory has changed, but not exactly what. It would be nice is dvc status could be made more granular, returning something like

data.dvc:
    outputs:
        data/foo: new
        data/bar: deleted

instead of

data.dvc:
	changed outs:
		modified:           data

as it is today.

Thanks:)

we should be careful with this, imagine a directory with 1M new files. Probably we don’t want to show all of them. I would say we should show a summary by default or at least on some threshold (on number of changed files per directory)
