Brian Goff c7c95dc226 Adds ability to squash image after build ...

Allow built images to be squash to scratch.
Squashing does not destroy any images or layers, and preserves the
build cache.

Introduce a new CLI argument --squash to docker build
Introduce a new param to the build API endpoint `squash`

Once the build is complete, docker creates a new image loading the diffs
from each layer into a single new layer and references all the parent's
layers.
