* Fix gitlab

* Fix rotate tokens

* More fixes

* More fixes

* Fix tokens

* Fix basic auth tokens for kubeadm deployment.

* Tokens should be a dependancy on master, not nodes

* Set configure-cloud-routes=false as default if no network plugin is used

As configure-cloud-routes default value is `true`, so it need to be set to `false` when not required to avoid error messages like:
"Couldn't reconcile node routes: error listing routes: unable to find route table for AWS cluster" 
on, for example, AWS installations that don't use cloud native routing.

* Update kube-controller-manager.manifest.j2

remove extra spaces

This takes care of a few arbitrary use cases that may require custom mounts
inside of apiserver, controller manager, or scheduler.

Introduced variable node_taints which can be set in inventory for
specific hosts or in group_vars, which generates --register-with-taints
command line argument for kubelet.

* Update defaults to match k8s 1.12 suggestions

* Test if Netchecker works with node ip instead of localhost

* Update defaults to ipvs and coredns

* Update defaults for kube_apiserver_insecure_port

* Update main.yaml

Now the `kubespray-aws-inventory.py` script always set a node_labels key
to ansible_host.

When AWS instance did not set property labels, it would be an empty
string.

The TASK `Write kubelet config file (kubeadm or non-kubeadm)` will
failed with a msg:

`AnsibleUndefinedVariable: 'unicode object' has no attribute 'items'`.

* Switch to kubeadm deployment mode

Discuss:https://github.com/kubernetes-incubator/kubespray/issues/3301

* Add non-kubeadm upgrage to kubeadm cluster

* Add resource-container flag to kube-proxy manifest

* add resourceContainer: "" to kubeadm kube-proxy configs

Due to suboptimal external loadbalancer configs, the LoadBalancer
might point to a downed kube-apiserver that is not set up yet.

* Apply linux node selector to coreDNS deployment

* Remove comment before linux node selector on manifests

* mend

the ':' makes wrong return of calico_version after the calicoctl downloaded && before the cluster is up

* Remove Vault

* Remove reference to 'kargo' in the doc

* change check order

As Ubuntu Bionic Beaver uses systemd-networkd the step fails
if it tries to restart networking, as it is nonexistent.
