    [2184] Fix issue of null default value
    
    Found another issue which became more apparent now (but I think we've seen before); get_default_value() returns None if there is no default set, however, in some cases, None can be the actual default (datasources params for instance).
    
    This fix makes sure a default value of None is not confused with no value at all (which resulted in the error 'Error: data_sources/classes/IN[X]/params not found'

    [2184] support add/remove for any type
    
    deriving 'actual' type from the data that has been set; no change for primitive type, treat as lists if list, treat as named_set if dict.
    Elements of named sets and lists are themselves considered to be of the any type
