Adding an `exit` parameter for `WaiterMachine` to exit from current state

[prostomarkeloff]

✏️ Description ✏️

There was no way to look if the waiter machine is waiting for a message from a user. This is needed when cancelling a waiting or other fancy stuff.

The PR is too big cause of black formatting.

wm.is_waiting_for(bot.on.message, message.from_user.id)
