Definition of Done

• add check if intent is in domain.intents; otherwise emit UserWarning and raise RasaException or see below suggestion from @dakshvar22

@ancalita The error suggests that a training story consists of an intent which is not declared in the domain file. The proper fix for this will be to implement a check before policies are trained to verify that all intents from training stories are declared in the domain.

Received another alert this week: RASA-OPEN-SOURCE-DPH Wondering if we should move this to inbox since it occurs so frequently
