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.
