Aaron Lehmann 3e1a2d1f77 Avoid a HEAD request for each layer in a v2 pull ...

We were calling Stat for each layer to get the size so we could indicate
progress, but https://github.com/docker/distribution/pull/1226 made it
possible to get the length from the GET request that Open initiates.

Saving one round-trip per layer should make pull operations slightly
faster and more robust.
