Describe the solution you'd like

KTO has demonstrated superior performance to DPO in reasoning and is a great alternative to DPO (https://arxiv.org/abs/2404.02078). Can you please support the KTO implementation given its popularity?

Additional context

Original Non-NeMo implementation: https://github.com/ContextualAI/HALOs/blob/c69d008b0b724d0ef8f46a86bc405db1a2514d8e/trainers.py#L790
