Description of the change
Modifies the default service port name for redis services to allow for istio sidecar injection and mtls.
Benefits
Allows for the use of istio service mesh with sidecar injection and mtls enabled without post chart modifications to the services.
Applicable issues
Additional information
With the current configuration of the chart istio does not create a direct endpoint for each redis pod. This means that direct ip communication ends up hitting the PassthroughCluster. With the modification of service name a direct ip endpoint is created and istio with mtls can be used.
