the configuration file of the specified node (identified by `node_id`). If
`node_id` is not specified, returns the configuration of the directly connected
DataNode.
Adding the `all` parameter returns all configuration items (the `value` of
unconfigured items is `null`).
Adding the `with desc` parameter returns configuration items with descriptions.
