## Summary
Airflow 3.0 removes various deprecated functions, members, modules, and
other values. They have been deprecated in 2.x, but the removal causes
incompatibilities that we want to detect. This PR deprecates the
following names.
* in `DAG`
* `sla_miss_callback` was removed
* in `airflow.operators.trigger_dagrun.TriggerDagRunOperator`
* `execution_date` was removed
* in `airflow.operators.weekday.DayOfWeekSensor`,
`airflow.operators.datetime.BranchDateTimeOperator` and
`airflow.operators.weekday.BranchDayOfWeekOperator`
* `use_task_execution_day` was removed in favor of
`use_task_logical_date`
