Adding/replacing a node

Modified from comments in #3471

Limitation: Removal of first kube_control_plane and etcd-master

Currently you can't remove the first node in your kube_control_plane and etcd-master list. If you still want to remove this node you have to:

1) Change order of current control planes

Modify the order of your control plane list by pushing your first entry to any other position. E.g. if you want to remove node-1 of the following example:

  children:
    kube_control_plane:
      hosts:
        node-1:
        node-2:
        node-3:
    kube_node:
      hosts:
        node-1:
        node-2:
        node-3:
    etcd:
      hosts:
        node-1:
        node-2:
        node-3:

change your inventory to:

  children:
    kube_control_plane:
      hosts:
        node-2:
        node-3:
        node-1:
    kube_node:
      hosts:
        node-2:
        node-3:
        node-1:
    etcd:
      hosts:
        node-2:
        node-3:
        node-1:

2) Upgrade the cluster
