This changes the way Kubernetes nodename is computed: it is set by the controller based on the hostname and machine configuration, and pulled from the resource when needed. Kubelet client now also uses nodename to fix the certifcate mismatch issue on AWS. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
