--- upgrade: - | Kolla Ansible no longer sets ``show_multiple_locations = True`` by default when Glance's Ceph RBD backend is enabled.

On the other hand, these optimisations might have been causing other operators' trouble. Please see the linked bug report. Operators relying on this feature can set the flag themselves using service config overrides. `LP#1992153 `__ fixes: - | Kolla Ansible no longer sets ``show_multiple_locations = True`` by default when Glance's Ceph RBD backend is enabled.
