Use OpenStack image for Brightbox

The special Brightbox image uses the OpenStack userdata in Ignition but
lacked Afterburn usage. It actually works to use the OpenStack image and
directly which also enables Afterburn, thus we can drop the special
image.
Don't build a special image for Brightbox but recommend to use OpenStack
images directly. A symlink is added to help with the download of
hardcoded user scripts.

+- Brightbox: The regular OpenStack image should now be used, it includes Afterburn for instance metadata attributes
+- OpenStack: An uncompressed image is provided for simpler import (since the images use qcow2 inline compression, there is no benefit in using the `.gz` or `.bz2` images)
