Adding metadata for dietclassifer

[matan_zuckerman (matan)]

I have metadata parameter (the status of the message) for each message in my intents nlu ymal file. Those statuses can help DIETclassifier be better in its work (as even similar texts can be classified to different intents based on the status). How do I add it to the model? that DIETclassifier will take this parameter into account in its training and inference? Thank you for your help.
