To Reproduce Steps to reproduce the behavior:

1. Deploy RHOSP, preferably from an older version such as 13
2. Perform updates and upgrades

Expected behavior

• Ironic overcloud images should be cleaned up after updates and upgrades

Bug impact

• Increased filesystem usage might cause a pre-upgrade validation to fail, preventing upgrade to RHOSP 17.1

Known workaround

• Manually delete older images in the undercloud
