`test_authentication.py` test suite is failing on setup with `ccmlib.node.TimeoutError` error, on scylla ver. 3.28.2 and 3.29.3

Empieza por tests/integration/standard/test_authentication.py, especialmente setup_module(), y tests/integration/init.py:start_cluster_wait_for_up(). Reproduce el fallo en Scylla 3.28.2 y 3.29.3; después, inspecciona el system.log de node1 y la ejecución de Argus vinculada para determinar por qué el arranque no alcanza el patrón de log esperado. Se considera terminado cuando la configuración de autenticación se completa y la suite de pruebas pasa.

test_authentication.py test suite is failing on test setup when starting scylla, with the following stacktrace:
