27b02d0913 Fix kubelet unit test; populate NodeName 
When we build a Kubelet directly we need to populate NodeName
as well as hostname, because we bypass the functions that normally
do this for us.

dee8d4b90b For kubelet, differentiate between the nodeName and the hostname 
This will allow us to use a nodeName that is not the hostname,
for example on clouds where the hostname is not the natural identifier
for a node.

7748a02e37 Eliminate possible infinite loop in exec 
If a user starts an exec session with a shell and leaves it idle long
enough, they will eventually hit the Kubelet's HTTP server's read/write
timeout of 5 minutes. At this time, the StartExec call to Docker exits,
but if the user requested a TTY, the exec'd process does not exit.
After StartExec finishes, we try to determine the exit code of the
exec'd process, but in this case, we'll never get it. This change exits
the loop after 5 tries if the process is still running.

a826529573 Insert 'svc' into the DNS search paths 
Fixes #8569.

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.

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.

f4e2c738f6 Delete deprecated API versions 
pkg/service:

There were a couple of references here just as a reminder to change the
behavior of findPort. As of v1beta3, TargetPort was always defaulted, so
we could remove findDefaultPort and related tests.

pkg/apiserver:

The tests were using versioned API codecs for some of their encoding
tests. Necessary API types had to be written and registered with the
fake versioned codecs.

pkg/kubectl:

Some tests were converted to current versions where it made sense.

2f503c57a5 nodecontroller: improve node status event recording 
This patch substitutes the misleading reason "unknown" for the event
recording. For symmetry with kubelet's message "online" the conditions
Unknown and False are reported as "offline".

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.

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).

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.
