[performance-replication] Missing ingress for cluster_address

We need a additonal ingress ressource to provide for performance cluster the cluster_address endpoint. At the moment you must create a additional service that expose 8201

Start by locating the Vault Helm chart's existing ingress templates and related values. Trace how services expose the cluster_address endpoint and add the requested performance-cluster ingress so port 8201 does not require a separately created service; verify the rendered chart output.
