[stable/redis-ha]: Allow DNS requests to local network

- In some situations (GKE cluster with [Cloud DNS](https://cloud.google.com/kubernetes-engine/docs/how-to/cloud-dns#architecture)), the DNS server is configured on the local network IP range (169.254.0.0/16), so we should allow this CIDR in the default network policy.
