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.
