Fix istio Operator-less handling

General MR

Summary

• Adds support for Istio Operator-less enabled deployments and the dynamic creation of the following resources: Network Polices, Virtual services, and Authorization Policies.

• Resource configurations are dynamically set depending on wether .values.bigbang.istio or .values.bigbang.istiod are enabled.

• Following the merge of this MR, templating will be added to the BB MR that applies istio-injection=true labelon package namespaces when istiod is enabled. Example in the BB branch istiod-wrapper-and-package-templating
