0c52f7b6a5 Move CreatePodInfraContainer to DockerManager. 
This will allow us to start making it an implementation detail of the
Docker runtime.

6c98b9daee kubelet/metrics: Move instrumented_docker.go to dockertools. 
This can solve the circular import problem when we move the
kubelet.pullImage to kubelet/metrics or kubelet/container package.

b0e6926f67 kubelet: filter out terminated pods in SyncPods 
Once a pod reaches a terminated state (whether failed or succeeded), it should
not transit out ever again. Currently, kubelet relies on examining the dead
containers to verify that the container has already been run. This is fine
in most cases, but if the dead containers were garbage collected, kubelet may
falsely concluded that the pod has never been run. It would then try to restart
all the containers.

This change eliminates most of such possibilities by pre-filtering out the pods
in the final states before sending updates to per-pod workers.

af1e9f737f kubelet: Introduce volume manager. 
The volume manager book-keeps the information for the volume mounts
on the kubelet, so we can avoid passing the volumeMap around.

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.

the Docker daemon and for comparing 2 APIVersion objects.
