[ENH] Rate responses

[AlexanderNeumann]

One thing that should be done as soon as possible in the main branch of the bot framework:
Project partners want the option to rate the responses of the bot. For the implementation it first needs three minor adjustments:

1. Metamodel: Option to check for every response if it should provide a rating option
2. Code: If the option is checked, the restful service should send, similar to the button option, a boolean value indicating if a frontend should show rating options.
3. Code: Endpoint that the rating buttons trigger. A table in the database that should store the (optional?) user, inquiry, response, rating value, and an optional description for the rating.

Would it be possible to store them as monitoring messages? I think this could be a great qualitative mobsos metric for bots 🤓
