Merge pull request #47922 from dnardo/ip-masq-agent

Browse Source 
Automatic merge from submit-queue

Remove limits from ip-masq-agent for now and disable ip-masq-agent in GCE

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.
