Istio CNI decoupled from Openshift

Hi,

Would it be possible to decouple cni enablement from openshift parameters? We're using rancher and we would like to be able to turn on cni through your controlplane template, but information like cniBinDir and cniConfDir is hardcoded to fit openshift clusters and CNI chaining is also set to false without an ability to change it.

Would it be possible to expose those cni parameters as values similarly to how cni image is exposed?

Thanks!
