Add Operatorless support to core package Network Policies (Parent)

Description:

Currently ingress and Egress core package network policies have hardcoded namespaceSelector labels that only work with Istio Operator Deployments. This issue will track adding support for Istio Operatorless namespaceSelector labels that are dynamically passed from the Big Bang umbrella chart when istio3 (operatorless) is enabled.
