Matthew Mosesohn 9cb12cf250 Add autoscalers for dnsmasq and kubedns
By default kubedns and dnsmasq scale when installed.
Dnsmasq is no longer a daemonset. It is now a deployment.
Kubedns is no longer a replicationcluster. It is now a deployment.
Minimum replicas is two (to enable rolling updates).

Reduced memory erquirements for dnsmasq and kubedns
