This will allow us to migrate one TLD at a time by refreshing all zones on the specified TLD after dual-writing is enabled. Note that the TLDs parameter is required, which seems reasonable given that almost all imagined use cases would be on a by-TLD basis. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=160294546
