deafa44d61 kubelet: send all recevied pods in one update 
The kubelet sync loop relies on getting one update as the signal that the
specific source is ready. This change ensures that we don't send multiple
updates (ADD, UPDATE) for the first batch of pods. This is required to prevent
the cleanup routine from killing pods prematurely.

866c52c8a9 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.
