Some fundamental tools

## Objective
Add some fundamental pipe for manipulating node_list.

## Detail

We can add node of run to node_list with following command.

```sh
dpmanip -s add_run /path/to/run
```

We can add key and value to configure of run node with following command.

```sh
dpmanip -s add_conf /path/to/run key value
```

We can remove tag from node of path.

```sh
dpmanip -s untag /path/to/run tagname_or_project_path
```

Currently, untag does not remove the project node,
because the null project node is not defined yet.

This flag determine the behavior occured when there is no directory at the resolved path as follows:

- if `create_dir` is True: create new directory
- if `create_dir` is False: raise DataProcessorError
