search_images filter not working for all fields since >=0.99.0

[Maximilian Stinsky]

Greetings.

I was debugging a problem with the sdk when using search_images with filters where I am not able to filter for all existing fields.

What I found is that the problem was introduced with openstacksdk 0.99.0.

For example with >= 0.99.0 it is not possible to filter for attributed like protected, os_hidden, os_hash_algo and some more. Most importantly for us we are not able to filter on the properties dict anymore.

As an example we have images with the following property attached:
properties={'owner_specified.openstack.md5': '', 'owner_specified.openstack.sha256': '', 'owner_specified.openstack.object': 'images/Ubuntu 22.04 Jammy Jellyfish - Testing', 'description': '2022-08-09', 'source_hash': '465254c8a247de43f477b8b8928ee98b84e3d20df513d5e341bb2cd584d03580', 'uploaded_by': 'Image Uploader', 'stores': 'swift'}

With openstacksdk 0.62.0 it is possible to filter all images by the uploaded_by field like:
images = conn.search_images(filters={ "properties": { "uploaded_by": "Image Uploader" } })

Using version >= 0.99.0 the same filter results in an AttributeError which is triggered by [1]. The same AttributeError is triggered for the other mentioned fields.

The only thing that I found so far which might have caused this is the following change [2].

Maybe someone with more know-how about the openstacksdk could have a look what is broken here.
Thanks in advance!
