Clayton Coleman 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.

Clayton Coleman 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.

Clayton Coleman 01f3785426 Add status.podIP as a valid downward API target
Getting the public IP a container is supposed to use is O(hard),
and usually involves ugly gyrations in python or with interfaces.
Using the downward API means that the IP Kube is announcing to
other endpoints is also visible inside the container for pods to
identify themselves.

Yu-Ju Hong 56f4605f47 kubelet: refactor SyncPods for better readability
Eventually we would like to replace the all-encompassing SyncPods function with
more well-defined, smaller functions. This would not only help with the
readability and profiling of the code, it'd also set in motion for the plans to
trigger pod worker individually based on the content of the pod updates.

This commit serves as the first step of that, while avoiding breaking all unit
tests by preserving the SyncPods function for the time being.

This is useful for tests to verify that pods are indeed deleted on nodes.

This requires the DNS server to be running kube2sky v1.6 or higher (part of
release 0.18).  Users with older kube2sky MUST NOT update to this kubelet until
they upgrade DNS.  Versions of kube2sky >= 1.6 support both old and new style
names.  Old style names are deprectaed and will be removed around the time of
kubernetes v1.0 release.

Clayton Coleman 72ee028cab Gracefully delete pods from the Kubelet
This commit wires together the graceful delete option for pods
on the Kubelet.  When a pod is deleted on the API server, a
grace period is calculated that is based on the
Pod.Spec.TerminationGracePeriodInSeconds, the user's provided grace
period, or a default.  The grace period can only shrink once set.
The value provided by the user (or the default) is set onto metadata
as DeletionGracePeriod.

When the Kubelet sees a pod with DeletionTimestamp set, it uses the
value of ObjectMeta.GracePeriodSeconds as the grace period
sent to Docker.  When updating status, if the pod has DeletionTimestamp
set and all containers are terminated, the Kubelet will update the
status one last time and then invoke Delete(pod, grace: 0) to
clean up the pod immediately.

Yu-Ju Hong 2bf0646c76 Kubelet: do not remove directories of terminated pods
We recently changed `SyncPods` to filter out terminated pods at the beginning
for two reasons:

 * performance: kubelet no longer keeps goroutines to checks containers for
   terminated pods.
 * correctness: kubelet relies on inspecting dead containers to generate
   pod status. Because dead containers may get garbage collected and
   kubelet does not have checkpoints yet, syncing terminated pod could
   lead to modifying the status of a terminated pod.

However, even though kubelet should not *sync* the terminated pods, it
should not attempt to remove the directories and volumes for such
pods as long as they have not been deleted. This change fixes aggresive
directory removal by passing all pods (including terminated pods) to the
cleanup functions.

Yu-Ju Hong 050b8ba60b Kubelet: move active deadline check to per pod worker
Per-pod workers have sufficient knowledge to determine whether a pod has
exceeded the active deadline, and they set the status at the end of each sync.
Move the active deadline check to generatePodStatus so that per pod workers
can update the pod status directly. This eliminates the possibility of a race
condition where both SyncPods and the pod worker are updating the status, which
could lead to temporary erratic pod status behavior (pod phase: failed ->
running -> failed).

Yu-Ju Hong 25668ccc11 Kubelet: remove the getPodstatus method
Pod statuses are periodically writtien to the status manager, and status
manager sets the start time of the pod. All non-status-modifying code should
perform cache lookup and should not attempt to generate pod status on its own.

Yu-Ju Hong a2d04a84de kubelet: filter out terminated pods before rejecting pods
Currently, kubelet doesn't filter out terminated pods before determining whether

change fixes that.

This change also groups all related pod fitness checking functions into one
function to improve readability.
