|Titel||Replace factory_settings and ..._default_levels with "default_params" in check_info|
|Status||Done (Won't Do)|
We can now remove the ..._default_levels in the checks because almost no one uses them in main.mk manually. WATO does not need them. So rather introduce a new optional key default_params in check_info["foo"] for setting default params. If the type of those is dict, then merging takes place and the discovery function must return a dict as params. If the type is not dict, then not merging takes place in the discovery function can return None -> default params are being used, or any other value -> that is being used.
