This will only affect the tools service, the primary use case being (1) I go to
create a domain through nomulus tool, realize it's premium, (2) update the
premium list to not include that domain, (3) kill the tools service instance to
wipe out the cached premium value, then (4) create the domain at standard. This
commit eliminates step 3.
