Monitoring - Add Istio Operatorless Network Policy support

General MR

Summary

MR adds support for package network policies to work with Istio Operatorless deployments. Introduced changes do not impact standard Big Bang deployments with Istio Operator. :

• Modifies default ingress/egress policies for Monitoring to set dynamic namespaceSelector labels in place of hardcoded istio-controlplane labels that currently only work with Istio Operator deployments.
• If values is not set or found the label will default to istio-controlplane
• BB Pipeline Test
