* Update docs/submodules/releng-xci from branch 'master'
  - Merge "xci: Add k8-nosdn-nofeature role"
  - xci: Add k8-nosdn-nofeature role

    Move default k8s-cluster.yml from kubespray/files/ to
    role/k8-nosdn-nofeature/files/k8s-cluster.yml since it's scenario
    specific. Moreover, we set 'cloud' as kube_network_plugin, which would
    use kubnet as network plugin. The kubenet network plugin requires
    routing between to be setup by the administrator so we need to add
    static routes on every host since they are connected using a bridge
    instead of a router.
