This is built on top of #9250, and is related to both #9238 and #8949:
BlueprintResourceAllocatorinternalsExternalIpPolicytype; today it holds a couple of IP pools and a set of external DNS IPs, but it gives us a cleaner place to integrate all the IP pool work that @bnaecker is doing with ReconfiguratorSince we don't actually have external DNS IPs in a policy anywhere, this adds
DataStore::external_dns_external_ips_specified_by_rack_setup()(which is implemented as "load the current target blueprint and scan it for external DNS zones"; i.e., exactly what the builder was doing before). We should eventually delete this method once it's possible for an operator to reconfigure the external DNS IPs, but this lets the planning input build up the policy as though we already had this information available, more or less. Other than that new method, almost all the changes in this PR are to tests; the non-test changes are pretty minimal.
