REST service to delete an existing Rasa form

[turnerrainer]

AS AN Architect I WANT to have a REST service to delete an existing Rasa form SO THAT there wouldn't be duplicate services for it

Acceptance Criteria

Temporary list of endpoints - https://github.com/buerokratt/Buerokratt-onboarding/issues/8 Proto to add new Rasa forms

• [x] Use POST endpoint /rasa/forms/delete to delete an existing form
• [x] Apply changes on Rasa domain.yml
• [x] Deleting a form is forbidden if #96 responds with HTTP 200 for a request to find a matching form
• [x] Deleting a form is forbidden if #97 responds with HTTP 200 for a request to find a matching form
• [ ] When deleting a form, all of its sub-content gets deleted as well
• [ ] Changes apply only in case a form with an input name provided (form_name) already exists
• [ ] In relation to https://github.com/buerokratt/Training-Module/issues/85

Example

Initial input

forms:
  custom_fallback_form:
    required_slots:
        - affirm_deny
  direct_to_customer_support_form:
    required_slots:
        - affirm_deny

Output after a request to delete custom_fallback_form

forms:
  direct_to_customer_support_form:
    required_slots:
        - affirm_deny

Short summary: unable to delete a form even though it says that Form deleted. If I check the request response then it says "Can't find form to delete." Expected result: the form should be deleted if you select yes on the notification and it is not forbidden Real result: there is a notification saying that the form is deleted, but it is still there How to reproduce: login and go to https://admin.dev.buerokratt.ee/training/training/forms , then try to delete the first form in the list.

Seems to work as intended!
