[Libosinfo] [osinfo-db PATCH v4 01/10] schema: Add support for pre-installed images

[Fabiano Fidêncio]

Let's create a new element called "image", which will be added to the
"os" element.

By adding the new "image" element, we'll start supporting pre-installed
images, at least in order to provide their link to Apps consuming
osinfo-db.

The xml entry will be similar to:
<os>
  <image arch="x86_64" format="raw">
    <variant id="cloud"/>
    <url>https://download/foo/bar.img</url>
  </image>
</os>

Mind that the "variant" is an optional element.
