In BF-16732, the aggregation_secondary_reads suite is timing out because the 'CleanEveryN' task is taking 3-4 minutes to complete and is configured to run after every test as opposed to every 10 or 20 tests. As such, the n value of CleanEveryN should be raised so that the task runs less frequently.

Additionally, this suite runs on the small variant of each build variant that it runs on. To mitigate any memory issues, the suite should be configured to run on the 'large' variant of each build variant that it currently runs on.
