Inconsistent Size in image JSON

[titanous]

Size is capitalized and always 0, but there is an x-docker-size header that is set.

@stevvooe is this fixed in registry v2 api
re: #9015

[stevvooe]

@jfrazelle Yes. The size is reported for all api responses as Content-Length, avoiding inconsistencies. This can be retrieved with HEAD request to the layer resource if its required before downloading.

We are also discussing the details of size reporting for manifest dependencies in distribution/distribution#62, which I believe @titanous is familiar with.

[jessfraz]

so can I close this as a dupe of #9105?
if its ok w @titanous
