Resource managemernt

[SQL-enwiki]

Implement a resource management system using the groundwork laid in stats.php

As a user uses 5% of our current lowest provider's allowed queries, start throttling / delaying requests more aggressively until they reach 10%, at which point no further queries will be allowed until the beginning of the next calendar month.

Possible alternate would be adding hourly/daily/monthly hard limits per user. This may be preferable to intentionally degrading the service, as well as being easier to implement.

Not needed due to a successful grant request.

It may be worth revisiting this. We've run out of ipstack montly queries, and getipintel daily queries. GetIPIntel has graciously donated us a higher limit key.

Possibly a 500 query per user limit? That seems pretty reasonable at the moment, most of the heaviest users only get to just under 1/2 of that.
