Update K8s manifests with rolling upgrade for calico/node Daemonset

[tmjd]

With the rolling upgrade capability of Daemonsets in kubernetes 1.6 we can enable that in our manifests and change our Upgrade story for calico/node.

We should document how to do this, but I'm not entirely sure we want to enable the rolling-update in our checked-in manifests across the board - it should be a deliberate action on the users behalf to trigger this behavior.

EDIT: Maybe we do want to enable it. Open to hearing arguments for it :)

Let's do this in the next release. DaemonSet rolling-update support has been around long enough that I think it's safe, and is the desired behavior for most users.
