"""Clean old YAML configs.

The old config is not exactly the same as the current one. There might be extra keys or
missing keys. To make them compatible with the current one, we use the following script
to merge and reformat the old `config.yml`.

Please note that the configs are just used for reference and is not intended to be used
as input files for new training runs.
