bundle: introduce a "v3" spec
This is a small update from "v2", we use the freshly out of experimental
changelog version "03' format (alignment with bundle version is a coincidence) and we
now bundle phases by default.
We shall use v3 as the default bundle type later, when changegroup version '03'
is a bit more established
