* Add HA docs for API server. * Add auto-evaluated internal endpoints and clarify the loadbalancer_apiserver vars and usecases. * Use facts for kube_apiserver to not repeat code and enable LB endpoints use. * Use /healthz check for the wait-for apiserver. * Use the single endpoint for kubelet instead of the list of apiservers * Specify kube_apiserver_count to for HA layout Signed-off-by: Bogdan Dobrelya <bdobrelia@mirantis.com>
