[TAN-0084] Apply coupon code automatically if weather is bad

[lastralab]

Requirements:

• Create a cart rule that applies 20% discount to all products in cart using coupon code 'BADWEATHER' (1 use per customer)
• Use weather/temperature code to save temperature per registered users only [customer_id => customer_ip/temperature]
• Use the flag table to store that data
• Update flag entry every time the user logs in using the queue
• Update flag entry via cron job customizable from the backend, set default time to every hour (only for logged-in users)
• Create customization to apply cart rule for temperature range
• Update flag entry via CLI
• Show banner at the top of the page whenever the coupon link can be applied (meeting conditions based on temp range)
• Apply coupon code automatically as 'bad weather' limit to 50 coupons. The user has the option to open a link to apply it.
• User cannot apply coupon code manually, if applied, an event should be dispatched and an observer should verify the weather is indeed in the set range, but also has to check if code was applied previously for that user
• Add test unit
