In order to enable offline/intranet installation cases: * Move DNS/resolvconf configuration to preinstall role. Remove skip_dnsmasq_k8s var as not needed anymore. * Preconfigure DNS stack early, which may be the case when downloading artifacts from intranet repositories. Do not configure K8s DNS resolvers for hosts /etc/resolv.conf yet early (as they may be not existing). * Reconfigure K8s DNS resolvers for hosts only after kubedns/dnsmasq was set up and before K8s apps to be created. * Move docker install task to early stage as well and unbind it from the etcd role's specific install path. Fix external flannel dependency on docker role handlers. Also fix the docker restart handlers' steps ordering to match the expected sequence (the socket then the service). * Add default resolver fact, which is the cloud provider specific and remove hardcoded GCE resolver. * Reduce default ndots for hosts /etc/resolv.conf to 2. Multiple search domains combined with high ndots values lead to poor performance of DNS stack and make ansible workers to fail very often with the "Timeout (12s) waiting for privilege escalation prompt:" error. * Update docs.
