Celery 5.7.0 removed the `retry` decorator from `celery.backends.database`
(celery/celery#10130), so importing `celery_executor_utils` fails and
`CeleryExecutor` can't load. The provider allows `celery<6`, so a fresh install
picks up 5.7.0.
`BulkStateFetcher._query_task_cls_from_db_backend` now uses tenacity with
the same behavior as Celery's old decorator: up to 3 attempts on the same
SQLAlchemy errors, a warning before each retry, and the last error re-raised.
This works on every Celery version the provider supports. The integration test
that checks the retry log message is updated for tenacity's wording. I checked
the import and the `BulkStateFetcher` DB backend tests on Celery 5.6.3 and
5.7.0.
closes: #76590
