> Currently the DescribeStream AWS API used to get list of shards is has a restricted rate
limits on AWS. (5 requests per sec per account). This is problematic when running multiple
flink jobs all on same account since each subtasks calls the Describe Stream. Changing this
to ListShards will provide more flexibility on rate limits as ListShards has a 100 requests
per second per data stream limits.
