Stress test istio wrapper features

Currently wrapper has values for istio usage: https://repo1.dso.mil/big-bang/product/packages/wrapper/-/blob/main/chart/values.yaml#L31

This issue should include reviewing the templates (https://repo1.dso.mil/big-bang/product/packages/wrapper/-/tree/main/chart/templates/istio) and testing out each istio feature.

If any issues are found these should be fixed as part of this ticket. If any "tricky" things are discovered these should be documented to ease customer usage/adoption.
