parent node left by `get_children()` API calls.

- `path`: the path of the node to be deleted
- `version`: the expected node version (or `None` to ignore
version)

- `NoNodeException`: node to be deleted does not exist.
- `BadVersionException`: given version does not match the node's
version
- `NotEmptyException`: node cannot be deleted because it has
