The package groups which can be added in IMAGE_FEATURES don't have to
be (and I'd argue against it anyway) defined in the image. For Mentor,
we define them in our distro configuration.

That said, what we use them for is basically the same thing the tasks
in oe-core/meta-oe already provide, so we're looking to transition
away from that method to what upstream is using (tasks, or whatever we
end up using at the end of this discussion).
