Open redis access so the counters pods can access the redis backend

Redis is currently listening on 127.0.0.1 because services are running on that node. Services are currently getting migrated to pod in staging. But they will need access to this redis backend which will stay on that node. So open access so they can communicate.

This keeps the 127.0.0.1 address access too.
