This fixes the Redis StatefulSet e2e test by adding the missing `publishNotReadyAddresses: true` field, which was accidentially left out in #63742.

Without this fix, the redis e2e test will fail because the pod is unable
to lookup the service:

```
2018/09/14 13:57:10 lookup redis on 172.31.9.247:53: no such host
```
