It's weird to see RST_STREAM happen on a unary RPC. But who knows how that error propagates.

We do have google::cloud::internal::IsTransientInternalError(Status const& status), but we would have to teach the generator how to use it. https://github.com/googleapis/google-cloud-cpp/blob/f779bb99395bbdfe3aac51864ff2abf2a0b6dffc/google/cloud/internal/retry_policy.cc#L24-L38
