Create weather alert handler

[clement-pages]

Task description

A new feature of the Sunrise version is to alert the user when a weather alert is triggered by Meteo France (the national weather service in France). In a first time, to do that, the bot will send a webhook message to all discord servers that have enabled these features. This webhook will contain information about the thrown weather alerts such as level and type alert. For now, this new feature will be only available to the Haute-Garonne department.
