Existing Image Missing in Return of "list" Action

[Boris Lukashev]

We have encountered a situation in Glance where an image exists - we can see its UUID in the RBD store (raw image), we can see it via `openstack image show 5a014319-d1b1-456d-a4ed-dd4ce3ff2dac`, and we can reference it in TF files; but we cannot see it in Horizon unless we force its view action by UUID nor in the output of `openstack image list` or `glance list` CLI attempts.
Terraform builds depend on this image, so we dont want to delete it or we'll have to deal with TF modifications - plus that's no fix, just plastering over whatever caused this odd situation.
The image is for a Windows 2019 VM, raw format, with TPM enabled via hw:tpm_verion and hw:tpm_model options in the glance image properties. All other properties are baked-in standard Glance options. Removing the TPM custom options didn't help.
Stack is Wallaby, deployed via kolla-ansible, with Glance backed by Ceph Pacific (juju-deployed & managed).
Created a new image to make sure Glance is properly updating its image list and the new image does show up correctly. There's something about this specific image which "makes it different" enough to break list actions.

How can we reproduce this? Is there any chance you could provide a link to an image that causes this issue?

Thats the fun part - i'm not sure how to reproduce the problem.
We saw this a few times during Wallaby, not sure if its even an issue with Xena. IIRC in one case we figured out that Rabbit had somehow failed to deliver a completion notification, but in all cases the result was the same: Ceph was being "polluted" with images of which Glance was not aware after deciding it had failed to complete their creation for some reason or another.

This is not reproducible, more detailed information will be required to reproduce & fix the bug.
