[openstreetmap/openstreetmap-website] Convert database config to support reading from replicas (#2563)

Yes, these things might need checking (and at worst, we'll use the "manual connection switching" to a write connection, as described in the docs).

>From a brief check of the `users_controller#confirm` and `#confirm_email` methods then both already require a form to be submitted (as should be the case, since email clients and spam filters can auto-crawl links in emails).

I can't off-hand think of other situations where we are currently GETing something that involves database changes, but I'll have a look and see what I can find. If you can think of any then let me know!
