added the necessary CRD initialization step

[devfire]

Hi.

We need to initalize the CRDs before deploying istio. Otherwise it fails massively.

This is the command:

helm template install/kubernetes/helm/istio-init --name istio-init --namespace istio-system | kubectl apply -f -

We can deploy successfully.

Hi @devfire

Thanks for the contribution, as soon as I get some free time I will try it out and understandably merge :)
