default kube_proxy_mode in kubernetes-defaults

Use CNI to assign kube_pods_subnet for calico

Adding this into the default example inventory so it has less of a chance of biting others after weeks of random failures (as etcd does not  express that it has run out of RAM it just stalls).. 512MB was not  enough for us to run one of our products.

For etcdctl commands, use admin cert instead of node because this file
doesn't exist on etcd only hosts.

Remove redundant spaces

Now calico can be deployed if there are other existing pools
and not confuse IPAM and end up with pods in the wrong pools.
