[lib] Adding function upload_file_dir_ops() to io/utils.py

Adding a function upload_file_dir_ops() to upload file_dir_ops.py
to all clients. This is to remove the redundant code given below:
```
g.log.info("Upload io scripts to clients %s for running IO on "
           "mounts", cls.clients)
cls.script_upload_path = ("/usr/share/glustolibs/io/scripts/"
                          "file_dir_ops.py")
ret = upload_scripts(cls.clients, cls.script_upload_path)
if not ret:
   raise ExecutionError("Failed to upload IO scripts to clients %s" %
                        cls.clients)
g.log.info("Successfully uploaded IO scripts to clients %s",
           cls.clients)
```
