Fix performance penalty incurred by sending legacy formatted tars to the daemon

[natalieparellano]

See here - if we can, we should send an OCI formatted tar to the daemon. This will be true when we have all the layers (from first doing a docker image save).

The changes can be made here. We should just stream an OCI layout-formatted tar to the daemon instead of building up the image in the old format.
