Removing this stanza from the config will cause sandbox to write to production
cloud dns, which is what we want.
Likewise, exclude sandbox in addition to production in the create_cdns_tld
command from the environments that point to staging.
Cloud DNS has 3 environments that we would consider using:
- staging which is reset every week, so we can't use it for sandbox
- testing, which is not accessible from external App Engine
- production
Because of the difficulties with the first two, we've decided to use production.
