[openstreetmap/openstreetmap-website] Limit number of edits per user and day (#2342)

It regularly happens that people - usually, but not always new signups - upload hundreds of thousands of objects to OSM before someone notices and tells them to stop. Then we have to delete those hundreds of thousands of objects again. (Case in point from recent past, https://www.openstreetmap.org/user/maxiangying.) This is undesirable:
* it skews statistics ("wow, today was the day with the most edits since OSM started!!!" etc)
* it wastes processing time and bandwidth on the thousands of servers world wide that are configured to consume updates from OSM
* it wastes the time of volunteers who have to remove the edits
* it embarrasses the person who uploaded the data (at least I hope it does)

While editors can, and should, inform their users about potential issues, I think it would also be worth contemplating to have some sort of rate limit on the API. It could be something that users can override but not accidentally - for example, you could be normally limited to X edits per day (exact numbers t.b.d.) and then you could click a button in your user preferences that says "I have read the data import and mechanical edit guidelines and I want to lift the limitation for one week" or so.
