Fixing ingress controller daemonset on k8s < 1.9

[hyperbolic2346]

What this PR does / why we need it:
When we switched to an ingress daemonset, we didn't account for older installs. The api version changed on version 1.9, so anything pre-1.9 needs a different version. This PR makes the api version a template so we can change it depending on the version of k8s installed.
