Code Review

This pull request updates the integration tests for readonly_creds to support testing with rapid writes enabled, specifically targeting Pirlo buckets. It introduces configuration changes to run separate test suites for rapid writes and refactors the test runner to execute tests across different authentication methods. The feedback suggests addressing potential nil pointer dereferences in failure_during_file_sync_test.go by asserting that files are opened successfully. Additionally, it is recommended to refactor both the flag-set execution and the authentication method runner in creds.go to use t.Run subtests, which will isolate test failures and prevent abrupt process termination.
