[IMP] mail_bot: improve OdooBot workflow

This commit attempts to improve the workflow of the OdooBot onboarding
tutorial, as well as the answer given by the bot while idle.

These changes come from watching how users interact with OdooBot. To
improve the user's experience, the following changes have been made:

1. Move the attachment to the end of the tour, as it is where most
   people just close the bot.
2. Remove the quotation marks around commands that OdooBot tells the
   user to type, like "/" or ":)", as some users try to actually type
   the quotation marks too. Instead, use a light grey background around
   the command that the user should type.
3. Some users ask OdooBot questions, but the responses they get are
   useless. To solve this, use a message linking to the documentation or the
   videos when:
    - The user gives wrong answers twice for the same stage of the tour
    - The user talks again when the tour is completed
    - There's a question mark in the answer

To achieve this a "failed" state field is added on user model, allowing to
distinguish state in the bot workflow from state of answers (failed / not
failed).
