[ENH] Error status for bot actions

[lakhoune]

Currently, the bot actions are just executed but you cannot await for their result. In some cases, you may want to wait for the bot action to successfully pass before continuing the conversation state. Furthermore, we should also be able to handle cases where a bot action has failed. For example our service may want to return an error message to the user. Furthermore the failed attempts should also be logged in order to increase success awareness

One could also investigate the possibility to allow the service to manually set the state of the conversation. An example use case would be that the user wants to make a review but fails to include the canteen at which they had the dish. The service would send back a response to the bot telling it to send the message to the user "You forgot to specify the canteen. Could you pls specify it?" while the state should be manually set to the state where ChooseCanteen is enabled
