Twistlock - Add Dynamic Network Policy support

Description:

Currently many Ingress and Egress package network policies have hardcoded namespaceSelector labels. These hardcoded labels do not support the migration to Istio Operator-less deployments. This issue will track adding support for namespaceSelector labels that are dynamically passed from the Big Bang umbrella chart.

Implementation Guide Tasks:

• Setup Network Policies for Dynamic Values
• Validate Changes in a K3d Cluster with BB deployed and Istio Operator enabled
• Validate Changes in a K3d Cluster with BB deployed and Istio Operator-less (istioCore) enabled
• Add Required Templating in Big Bang Merge request

Hi @bimbola81 can you check that Add Required Templating in Big Bang Merge request were done. I merged this into BigBang, but I think we'll need a few more changes in the umbrella package. See here for details : big-bang/bigbang#2542

and this MR for an example: big-bang/bigbang!5895 (diffs)

You can open up a new MR in BigBang for the changes.
