AB#2074: Choosable K8S Version (#277)

Browse source 
AB#2074: Add configurable k8s version

Configurable version flow:
* cli config holds/validates k8sVersion
* InitCluster receive a k8sVersion arg
* InitCluster creates CM "k8s-version"
* kubeadm's InitConfiguration receives k8sVersion
* joinservice spec mounts/reads k8s-version CM
* joinservice supplies k8sVersion via JoinTicketResponse
Other changes:
* Remove unused test code (FakeK8SClient)
* move VersionConfig map to /internal/versions
* installk8sComponents is now a function instead of a method
