When a domain refreshes, always delete all of its subordinate host
records and then add glue records for its in-bailiwick nameservers, if
the domain is in a publishable status. When a host refreshes, delete
its glue record (if any) and then refresh its superordinate domain. The
goal is to prevent A/AAAA records for hosts that are not used as
in-bailiwick nameservers from being published in the DNS.
