We flatten the metadata so that it is easier to parse out of mlflow/run metadata. Because of this, a user's metadata key could overwrite the real key in the config that gets logged. This PR fixes that by simple erroring and asking the user to rename their metadata key. It also adds
flatten_metadata
to allow not flattening the metadata.Original run that overwrites the key:
metadata-with-error-4-G9ps3T
Run with duplicate key that now errors:
metadata-unflat-1-ltIBGL
Run without flattening metadata:
metadata-unflat-2-VoxpxS
