Subject: [PATCH] Scrap tool to fix DomainResource keys to deleted nameservers

There are about 25 active domains that have keys that point to deleted nameservers. In all cases, there are active nameservers with the same FQDN that these domains should be pointing to. Given the domains in question (pulled via BigQuery, see the bug), update the domain with the correct keys whenever a deleted host is found.
