Kubelet: wait until container runtime is up
...
Instead of waiting for the docker client to be up, we wait for the container
runtime to be up.

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.

We must not clear the pod directory in killUnwantedPods(), volumes are still
mounted there at this time. There already is cleanupOrphanedPodDirs(),
called later in the SyncPods() sequence, which should remove these pod
directories.

Move killPod() logic to DockerManager KillPod().
...
This moved Docker specific logic there and allows it to align with the
runtime API. There is still a pod infra container reference in the
function due to network plugins. We can handle this in the Kubelet since
we'll need to be explicit in stating that the network plugin will not
work in a non-Docker runtime.

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.
