config_list_from_json
This function attempts to parse JSON data from the given
env_or_file parameter. If env_or_file is an
environment variable containing JSON data, it will be used directly. Otherwise, it is assumed to be a filename,
and the function will attempt to read the file from the specified file_location.The
filter_dict parameter allows for filtering the configurations based on specified criteria. Each key in the
filter_dict corresponds to a field in the configuration dictionaries, and the associated value is a list or set
of acceptable values for that field. If a field is missing in a configuration and None is included in the list
of acceptable values for that field, the configuration will still be considered a match.Parameters:
