## copy_volume_file
```python
vessl.copy_volume_file(
   source_volume_id: Optional[int], source_path: str,
   dest_volume_id: Optional[int], dest_path: str, quiet: bool = False
)
```
Copy file either from local to remote, remote to local, or remote to
remote.

**Args**
* `source_volume_id` (Optional[int]) : Source volume file id. If not
    specified, source is assumed to be local.
* `source_path` (str) : If source_volume_id is empty, local source path.
    Otherwise, remote source path.
* `dest_volume_id` (Optional[int]) : Destination volume file id. If not
    specified, destination is assumed to be local.
* `dest_path` (str) : If dest_volume_id is empty, local destination path.
