Gate sends traffic to clouddriver-rw instead of clouddriver-ro-deck

[ezimanyi]

When using the kleat + kustomize deployment path, traffic from gate gets sent to clouddriver-rw instead of clouddriver-ro-deck.

This is because there is no override in the gate config file; traffic just goes to the generic clouddriver service, which points to clouddriver-rw. We'll likely need to add an override in the gate config (or come up with a more generic solution).
