This does not seem quite right to me. I don't think we want to be
enabling or disabling different services in images at deployment time.
That's one of the reasons that we have the element nature of
diskimage-builder, so that you can build an image with the software
components you want. Any service that you include in the image build
is automatically enabled. If you want that image with a service
disabled, you build a new image.
I think the implementation would be a little weird as well. How would
you disable a service in the image? You could mount and modify the
image before deploying, but that's quite a bit of added complexity of
downloading an image, modifying it, and saving it.
