Spending limit

[QuiiBz]

We should add a spending limit to Lagon Cloud, that prevents unexpected and unwanted bills.

This limit can be added per function and/or per organization and corresponds to a certain number of requests made during the month. When approaching the limit, the user should get warnings on the dashboard and by email.

Example

Let's assume I don't want to pay more than 5€ for requests served per month because my traffic is relatively low. This corresponds to 5,000,000 requests, so I'll add this limit on the Dashboard.

One day, my project suddenly get a lot of traffic. A warning is triggered when reaching 75% of my limit (3,750,000 requests for me), and another one at 90% (4,500,000 requests for me).

I can choose to raise or disable the limit to make sure every user is able to access my project, or I can keep the limit to avoid spending too much (but that means when reaching the 5,000,000th request, the Function will be disabled).
