2bf0646c76 Kubelet: do not remove directories of terminated pods 
We recently changed `SyncPods` to filter out terminated pods at the beginning
for two reasons:

 * performance: kubelet no longer keeps goroutines to checks containers for
   terminated pods.
 * correctness: kubelet relies on inspecting dead containers to generate
   pod status. Because dead containers may get garbage collected and
   kubelet does not have checkpoints yet, syncing terminated pod could
   lead to modifying the status of a terminated pod.

However, even though kubelet should not *sync* the terminated pods, it
should not attempt to remove the directories and volumes for such
pods as long as they have not been deleted. This change fixes aggresive
directory removal by passing all pods (including terminated pods) to the
cleanup functions.

longer needed.

a2d04a84de kubelet: filter out terminated pods before rejecting pods 
Currently, kubelet doesn't filter out terminated pods before determining whether
a pod fits. This could lead to duplicated events for rejecting the pods. This
change fixes that.

This change also groups all related pod fitness checking functions into one
function to improve readability.

need to pass the ipcMode or netMode via RunContainerOptions.

2cf0dfb79d Handle out of disk situation on kubelets. 
Kubelet will stop accepting new pods if it detects low disk space on root fs or fs holding docker images.
Running pods are not affected. low-diskspace-threshold-mb is used to configure the low diskspace threshold.

1ad4dd7803 Kubelet: replace DockerManager with the Runtime interface 
This change instructs kubelet to switch to using the Runtime interface. In order
to do it, the change moves the Prober instantiation to DockerManager.

Note that most of the tests in kubelet_test.go needs to be migrated to
dockertools. For now, we use type assertion to convert the Runtime interface to
DockerManager in most tests.
