Review Comment:
Similarly here: https://github.com/apache/airflow/pull/30244 - it almost
seems that even if the waiter implementation in botocore does not provide any
way to get callback while waiitng, we could have a wrapper around the waiter
that could be used across many of the Deferrable Amazon operators (this would
become super useful in 2.6.0 with the triggerer logs interleaved with task
logs).
