* Fixes #18663. Bad handling of existing config in dellos9 module. The dellos9 module doesn't build correctly the internal structures used to represent the existing config of the managed network device. This leads to apply changes every time the playbook is run, even if the existing config is the same that the one you are trying to push into the device. Probably this problem exist also in the dellos6 and dellos10 modules, but I only fixed it in the dellos9 module. The fix modifies two methods. The first one is `get_config`, where the return clause didn't work correctly when the flow doesn't enter in the `if` block. In that case the `contents` variable is not an array an this should be handled. The second fix is in the `get_sublevel_config` method. In this case the indentation whitespaces of the parents should be rebuild because further functions and methods required it to handle correctly comparisons used to check if changes should be pushed into device. * Fixes #18663 for dellos10 module with the same patches as dellos9.
