Similar to 943f46c425c0916296f5478d0aa3de6c660c9bbd; slight change
in behavior, because previously, other errors would not be retried,
but also didn't mark the check as failed.

Define a type to help discovery, and update the signatures of
`ResolveName`, `Network.ResolveName`, and `Sandbox.ResolveName`
accordingly.
