275002173e Kubelet: parallelize cleaning up containers in unwanted pods 
Kubelet kills unwanted pods in SyncPods, which directly impact the latency of a
sync iteration. This change parallelizes the cleanup to lessen the effect.

Eventually, we should leverage per-pod workers for cleanup, with the exception
of truly orphaned pods.

Use go-dockerclient's APIVersion to check the minimum required Docker
version, as it contains methods for parsing the ApiVersion response from
the Docker daemon and for comparing 2 APIVersion objects.

fd34441d2d Kubelet: persist restart count of a container 
Currently, restart count are generated by examine dead docker containers, which
are subject to background garbage collection. Therefore, the restart count is
capped at 5 and can decrement if GC happens.

This change leverages the container statuses recorded in the pod status as a
reference point. If a container finished after the last observation, restart
count is incremented on top of the last observed count. If container is created
after last observation, but GC'd before the current observation time, kubelet
would not be aware of the existence of such a container, and would not increase
the restart count accordingly. However, the chance of this should be low, given
that pod statuses are reported frequently. Also, the restart cound would still
be increasing monotonically (with the exception of container insepct error).

bb417e82d7 Kubelet: surface the container creation/start failure reason 
Container creation/start failure cannot be reproduced by inspecting the
containers. This change caches such errors so that kubelet can retrieve it
later.

This change also extends FakeDockerClient to support setting error response
for a specific function.
