Yu-Ju Hong a68f534264 kubelet: fix duplicated status updates at pod cleanup 
cleanupTerminatedPods is responsible for checking whether a pod has been
terminated and force a status update to trigger the pod deletion. However, this
function is called in the periodic clenup routine, which runs every 2 seconds.
In other words, it forces a status update for each non-running (and not yet
deleted in the apiserver) pod. When batch deleting tens of pods, the rate of
new updates surpasses what the status manager can handle, causing numerous
redundant requests (and the status channel to be full).

This change forces a status update only when detecting the DeletionTimestamp is
set for a terminated pod. Note that for other non-terminated pods, the pod
workers should be responsible for setting the correct status after killling all
the containers.

Yu-Ju Hong 3072754c8b Avoid unnecessary GET request when updating pod status 
When sending out an pod status update, kubelet

GETs the pod from the apiserver
Terminates if the apiserver returns an not found error; otherwise, proceed to
to update.
Even after a pod has been deleted, there might still be queued up updates for
the pod. This leads to expensive, unncessary GET operations. The situation is
worse when there are batch creation/deletion of a significant number of pods
(e.g., E2E tests), leaving many updates in the queue.

This change checks whether a pod exists before GET the pod from the apiserver
to avoid redundant GETs.
