ip-masq-agent when issuing an iptables-save will read
any configured iptables on the node. This means that
the ip-masq-agent's memory requirements would grow
with the number of iptables (i.e. services) on the node.
Disable ip-masq-agent in GCE

setting the non-masq-cidr in the kubelet to 0.0.0.0/0 we
need to ensure the ip-masq-agent runs.
Add node label pre-req back to ip-masq-agent.
Make gce test consistent with gce default scripts.
Automatic merge from submit-queue
Add some initial resource limits to the ip-masq-agent.
These limits were based on observing the agent over roughly a day RES was typically ~4M for me but I'd like to make sure we have some headroom. If there was a huge config map then this could increase slightly but not significantly since we only allow 64 entries.
