Poll a job until it is ready, with a deadline
A report service starts a job and you poll is_ready() until it says yes. Write wait_until_ready(is_ready, interval, deadline): await is_ready(); if it isn't ready, sleep interval seconds and ask again. Return how many times you asked. If the job isn't ready within deadline seconds, raise TimeoutError (without asking again after the deadline).
