Hi Miguel,

i'm not subject matter expert but here's some relevant info:

* overcloud_prep-containers.sh is not a production thing, it's 
automation from TripleO Quickstart, which is not part of production 
deployments. We shouldn't depend on it in docs/automation for OVN migration.

* For production envs, the image preparation steps used to be documented 
and performed manually. This now is now changing in Rocky+, as Steve 
Baker integrated the image prep into the deployment itself. There are 
docs about the current method [3].

* I hit similar issues with incorrect Neutron images being uploaded to 
undercloud registry, you can try deploying with this patch [4] which 
aims to fix that problem (also the depends-on patch is necessary).
