[AIRFLOW-5218] Less polling of AWS Batch job status (#5825)
[AIRFLOW-5218] Less polling of AWS Batch job status (#5825)

https://issues.apache.org/jira/browse/AIRFLOW-5218
- avoid the AWS API throttle limits for highly concurrent tasks
- a small increase in the backoff factor could avoid excessive polling
- random sleep before polling to allow the batch task to spin-up
  - the random sleep helps to avoid API throttling
- revise the retry logic slightly to avoid unnecessary pause
  when there are no more retries required
