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.

0c5c3d8bb9 Remove pkg/util/mount (moved out of tree) 
This patch removes pkg/util/mount completely, and replaces it with the
mount package now located at k8s.io/utils/mount. The code found at
k8s.io/utils/mount was moved there from pkg/util/mount, so the code is
identical, just no longer in-tree to k/k.

367f879131 Retire mount.Exec for k8s.io/utils/exec 
This patch removes mount.Exec entirely and instead uses the common
utility from k8s.io/utils/exec.

The fake exec implementation found in k8s.io/utils/exec differs a bit
than mount.Exec, with the ability to pre-script expected calls to
Command.CombinedOutput(), so tests that previously relied on a callback
mechanism to produce specific output have been updated to use that
mechanism.

1fd8921546 Move mount/fake.go to mount/fake_mount.go 
This patch moves fake.go to mount_fake.go, and follows to principle of
always returning a discrete type rather than an Interface. All callers
of "FakeMounter" are changed to instead use "NewFakeMounter()". The
FakeMounter "Log" struct member is changed to not be exported, and
instead only access through a new "GetLog()" method.
