924553b7ee iptables don't do reverse DNS lookups 
the iptables monitor was using iptables -L to list the chains,
without the -n option, so it was trying to do reverse DNS lookups.
A side effect is that it was holding the lock, so other components
could not use it.
We can use -S instead of -L -n to avoid this, since we only want
to check the chain exists.

b252865479 kubelet: Avoid sending no-op patches 
In an e2e run, out of 1857 pod status updates executed by the
Kubelet 453 (25%) were no-ops - they only contained the UID of
the pod and no status changes. If the patch is a no-op we can
avoid invoking the server and continue.

51814ae189 Be more agressive acquiring the iptables lock 
iptables has two options to modify the behaviour trying to
acquire the lock.

--wait  -w [seconds]    maximum wait to acquire xtables lock
                        before give up
--wait-interval -W [usecs]  wait time to try to acquire xtables
                            lock
                            interval to wait for xtables lock
                            default is 1 second

Kubernetes uses -w 5 that means that wait 5 seconds to try to
acquire the lock. If we are not able to acquire it, kube-proxy
fails and retries in 30 seconds, that is an important penalty
on sensitive applications.
We can be a bit more aggresive and try to acquire the lock every
100 msec, that means that we have to fail 50 times to not being
able to succeed.
