Add the ability to override the service port name

[mmastersvz]

Add into https://github.com/castai/helm-charts/blob/main/charts/castai-pod-node-lifecycle/templates/service.yaml#L9-L16 a variable to override the service port name.

When using istio the current port name results in IST0118. See https://istio.io/latest/docs/reference/config/analysis/ist0118/#how-to-resolve

values.yaml

  service:
    portNames:
      https: "https"
      metrics: "metrics"

service.yaml

  ports:
    - name:  {{ .Values.service.portNames.https }}
      protocol: TCP
      port: 443
      targetPort: https
    - name:  {{ .Values.service.portNames.metrics }}
      protocol: TCP
      port: 9090
      targetPort: 9090

Then can set it to override to eliminate IST0118

  service:
    portNames:
      https: "tcp-https"
      metrics: "tcp-metrics"
