Decouple Istio CNI driver with Openshift Parameter.

Feature Request

Why

I would like to enable the Istio CNI driver, without enabling OpenShift for the complete Big bang deployment. I would like another variable to be added, to enable Istio chart, and not for every subchart. The if statement for CNI could be OR'd with this variable. This is causing issues with other helm releases in my deployment. Many cloud CNI drivers work with the Istio CNI driver. It isn't obvious what the OpenShift variable is enabling in the chart. I haven't figure out a way to set openshift: true on just the Istio subchart? I have considered using a PostRenderer on the IstioOperator object.

It would also be nice to be able to add some variables for CNI config. Enabling chained being the one I used.

will likely be added to the 3rd operator-less Istio epic for features to be added after we have reached parity with the current Operator installed version of Istio
