Updated existing network policies to be more dynamic

General MR

Summary

• Removed duplicated network policies
  • The istio-allow.yaml that was removed contained two duplicate network policies. The first was a duplicate of the allow-to-istio-ingressgateway network policy and the second was a duplicate of the allow-istiod-egress network policy.
• Updated istiod egress and ingress from gateway network policies to be more dynamic in order to get it to work with both Istio implementations

Relevant logs/screenshots

**Note: istiod is now in istio-system namespace and gateways are now in istio-gateway namespace.
