+    Extraction of _create_ro_task() from being a nested function inside Ns.deploy().
+    The _create_ro_task() function is now a static method inside the Ns class. This
+    eases the testability of _create_ro_task().
+    With this extraction a unit test was introduced to cover the extracted function.
