Werk #12951: response format of all host_config/folder_config REST API endpoints

The response format of some host_config and folder_config endpoints did not fully conform to the OpenAPI spec. This has now been fixed, but this also means that the following endpoints

create folder hosts of folder update folder bulk update folders move a folder

bulk create hosts list hosts

will have a different format in SOME attributes on the attributes key within the "extensions" key. The now documented format in the OpenAPI documentation is the correct one now.
