Automatically upload composed images to the cloud

Currently, Azure, vSphere, and OpenStack are supported. See
weldr#826 for more details about this new
feature.

I've called the upload library "lifted" as a reference to Seuss'
The Lorax -- in the book, the Lorax lifts himself up by the seat of his
pants through a hole in the smog clouds, and they start calling him the
"Lifted Lorax."

This adds new features to the /compose route under API v1
