TestMTUNetworkCRUDL acceptance test is not deterministic #2592
Description
We compare objects returned from an Update operation, and retrieved from a Get. It seems like the updated_at field is not yet updated in the return of the Update, which could cause the comparison to fail.
See for example https://github.com/gophercloud/gophercloud/actions/runs/4414202596/jobs/7735607146#step:5:3886
