disk_layout: Improve documentation
In the .json file itself, add a list of changes from rev N-1 so that
people don't have to go diffing or digging through the history to
understand exactly what's different. In the readme file, update the
sentence describing how new layouts are named, and add "minios"
as a valid type.
