The ``AvailabilityZoneFilter`` was deprecated for removal
in 24.0.0 (Xena) and has now been removed.
The functionality of the``AvailabilityZoneFilter`` has been
replaced by the``map_az_to_placement_aggregate`` pre-filter.
The pre-filter was introduced in 18.0.0 (Rocky) and enabled
by default in 24.0.0 (Xena). This pre-filter is now always
enabled and the ``[scheduler] query_placement_for_availability_zone``
config option has been removed.
