Templates for kubeadm configuration

[kvaps]

Kubeadm configuration consists of 3 manifests:

# helm install foo kvaps/kubernetes --set persistence.enabled=false --set admin.job.enabled=false
# kubectl exec -ti deploy/foo-kubernetes-admin -- sh
# kubeadm init phase upload-config kubeadm --config /config/kubeadmcfg.yaml -v 10 2>&1 | sed -n 's/.*Request Body: //p'

There is a need to convert them to templates, possible parametrize and put into manifests directory
