    If my understanding is correct, this affects the add behavior, making it so that `targetNumExecutors`
can't increase until 60 seconds have passed or we've received all the initial requested executors.
    
    Can we change the logic to be that we don't reduce `targetNumExecutors` below initialExecutors
until either
    * a stage has been submitted
    * we've waited for `spark.dynamicAllocation.executorIdleTimeout` seconds
