This commit unifies OS container and ISO container images at OBS level. This way the two are stick together and we need to handle less submissions.

Also, as a consequence, both release numbers are likely to be aligned with this setup.

This PR removes the following OBS packages:

  • build-base-iso-image
  • build-baremetal-iso-image
  • build-baremetal-disk-image
  • build-kvm-iso-image
  • build-rt-iso-image
  • build-k3s-selinux-iso-image
  • build-rke2-selinuc-iso-image

And they are embedded in their SL-Micro-* counterpart.

Using the OS image as the builder itself simplifies the image cross dependencies, so the ISO only requires the OS container to build, so base ISO only requires base OS.

nit: we could consider adapting this replace_using_env OBS service to actually support globbing, so instead of requiring a new service call per file and per variable we could do something like the following (the * on the file name):

<service name="replace_using_env" mode="buildtime">
    <param name="file">Dockerfile*</param>
    <param name="eval">SLMICRO_VERSION=$(rpm --macros=/root/.rpmmacros -E %slmicro_version)</param>
    <param name="var">SLMICRO_VERSION</param>
  </service>

Note this same approach is also valid for disks

I'm not sure about using the OS images as builder (which probably contain lots of "build" dependencies, which are not "runtime" dependencies) 🤔

I agree this is arguable, but with the current setup installing elemental, which is part of the base image, already includes everything we need to build, which is not that much at the end.

This commit unifies OS container and ISO container images at OBS
level. This way the two are stick together and we need to handle less
submissions.

Also, as a consequence, both release numbers are likely to be aligned
with this setup.
