Improve logic for S3 stats gathering. Uses automatic SLOW_TESTS. (#53549)
Summary:
This PR:
1. refactors the logic for S3 stats gathering.
2. Renames SLOW_TESTS to TARGET_DET_LIST to disambiguate and remove confusion with slowTest
2. detects slow tests (tests with time > 5min) to add to the TARGET_DET_LIST based on results in S3 from the previous nightly.
