c075719f05 Kubelet: fix the runtime cache to not cache the stale pods
If a pod worker sees stale pods from the runtime cache which were retrieved
before their last sync finished, it may think that the pod were not started
correctly, and attemp to fix that by killing/restarting containers.
There are two issues that may cause runtime cache to store stale pods:
  1. The timstamp is recorded *after* getting the pods from the container
     runtime. This may lead the consumer to think the pods are newer than they
     actually are.
  2. The cache updates are triggered by many goroutines (pod workers, and the
     updating thread). There is no mechanism to enforece that the cache would
     only be updated to newer pods.

This change fixes the above two issues by making sure one always record the
timestamp before getting pods from the container runtime, and updates the
cached pods only if the timestamp is newer.

ec68f1a85a kubelet/rkt: Add docker prefix to image string.
This change makes rkt to run only docker image for now,
which enables us to test with all existing pods.

1511dbf0b5 Expose pod name as a label on containers.
Full pod name is exposed under key 'kubernetes.io/pod'.
It helps in introspection by looking at all containers in a pod through
docker ps -a -f label=kubernetes.io/pod=podXXX

We also plan to visualize this in cAdvisor.

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.

SyncPod subsumes RunPod, so the latter is no longer needed.
After this change, DockerManager implements the Runtime interface.

3b9eba2c1b Add SyncPod() to DockerManager and use in Kubelet.
This allows us to abstract away the logic of syncing a pod by the
runtime. It will allow other runtimes to perform their own sync as well.
