+Subject: [PATCH] Fix DatatransferObjectTest for Python 3.12
+
+This fixes a test error when run with Python 3.12:
+```
+Traceback (most recent call last):
+  File "pcs_test/tier0/common/interface/test_dto.py", line 41, in test_has_all_subclasses_are_dataclasses
+    _import_all(pcs.__path__)
+  File "pcs_test/tier0/common/interface/test_dto.py", line 31, in _import_all
+    loader.find_module(module_name).load_module(module_name)
+    ^^^^^^^^^^^^^^^^^^
+AttributeError: 'FileFinder' object has no attribute 'find_module'
+```
+Instead, use the spec-based APIs introduced in 3.4:
