    Return a list of the components of input_string when split using the specified delimiter. If strip_whitespace is not specified or is "True", strip all whitespace from the beginning and end of each resulting component.
    
    Args:
        input_string (CEF type: *): The string to split
        delimiter: The delimiter to split by, which defaults to a comma
        strip_whitespace: Either True or False to indicate whether or not to remove whitespace before and after each item. Defaults to True
    
    Returns a JSON-serializable object that implements the configured data paths:
        *.item (CEF type: *): One result for each output item
