[contrail-helm-deployer] Deprecate config-ingress and analytics-ingress services

Remove Kubernetes services "service-config-ingress" and "service-analytics-ingress" from Helm charts.

These services rely on selector "app:ingress-api" which is not used in the cluster deployment. Besides, these services are mapped to port 80 for the Config and Analytics nodes, however, such port is not enabled on these nodes.

In summary, these two services should be deleted as they are not used and could lead to confusion.
