Use stable k8s api versions for resource which have been promoted to GA for Gitlab Runner

I highly recommend to update kubernetes API endpoints to latest stable versions!

I've been looking only for Gitlab Runner and not other charts

DaemonSet, Deployment, ReplicaSet - are stable since kubernetes v1.9 and are in apps/v1

https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.9.md#apps

rbac.authorization.k8s.io API group is GA and v1 since kubernetes v1.8

https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.8.md#sig-auth

Also Kubernetes officially deprecates these non stable APIs
