780accb3ba Kubelet should garbage collect dead pods 
The sync loop should check for terminated pods that are no longer
running and clear them. The status loop should never write status
if the pod UID changes. Mirror pods should be deleted immediately
rather than gracefully.

89f1f3b1b8 Alter graceful deletion to not use TTL 
Avoid TTL by deleting pods immediately when they aren't
scheduled, and letting the Kubelet delete them otherwise.

Ensure the Kubelet uses pod.Spec.TerminationGracePeriodSeconds
when no pod.DeletionGracePeriodSeconds is available.

eb0fb43453 kubelet: Add image pulling event. 
Since it takes a while (1-2mins) for kubelet to pulling a big image
(>500MB). Just showing "Pending" for pod status is not very helpful.

This commit introduces a "pulling" event, and inserts it before the
kubelet starts to pull an image.

d6ff297a1f Kubelet: stop logging "Error on reading termination-log..." messages 
If a pod was deleted and the associated volumes/directory were removed, there
could be a window where the pod worker is still active. If the pod worker tries
to inspect the logs, such an error would be logged. Since the pod has been
deleted, such error messages are meaningless.

This change stops logging this error, but stores the error string in the pod
status. The pod status will be updated for pods that are still alive, and will
be discarded eventually for deleted pods.
