Yifan Gu 0a81443056 kubelet/rkt: fetch journal logs in json format. 
This enables more fine-grained control over the things we want to
output. Also by closing the stdout/stderr of the journalctl process
when user hits `Ctrl-C` after `kubectl logs $POD -f`, this enables
the journalctl process to exit.

Change all references to the container ID in pkg/kubelet/... to the
strong type defined in pkg/kubelet/container: ContainerID

The motivation for this change is to make the format of the ID
unambiguous, specifically whether or not it includes the runtime
prefix (e.g. "docker://").

Tim St. Clair 52ece0c34e Refactor readiness probing 
Each container with a readiness has an individual go-routine which
handles periodic probing for that container. The results are cached, and
written to the status.Manager in the pod sync path.

Andy Goldstein ed021fed4c Port forwarding fixes 
Correct port-forward data copying logic so that the server closes its
half of the data stream when socat exits, and the client closes its half
of the data stream when it finishes writing.

Modify the client to wait for both copies (client->server,
server->client) to finish before it unblocks.

Fix race condition in the Kubelet's handling of incoming port forward
streams. Have the client generate a connectionID header to be used to
associate the error and data streams for a single connection, instead of
assuming that streams n and n+1 go together. Attempt to generate a
pseudo connectionID in the server in the event the connectionID header
isn't present (older clients); this is a best-effort approach that only
really works with 1 connection at a time, whereas multiple concurrent
connections will only work reliably with a newer client that is
generating connectionID.

Yifan Gu 4309cafff1 rkt: return non error if the pod doesn't exist in GetPodStatus(). 
Previously, GetPodStatus() will return error if the pod is never
created. However we've never seen the sync loop fail because in the
beginning of the loop, if the pod is not found, it will be created.

This works fine except the pod that keeps crashing. Because the above
logic will keep restarting the pod as if it's never created.

This PR fixes the bug.

Jonathan Wills ad085f78fe If an isolator's request is nil, populate it with the limit and vice versa. 
The appc spec isn't currently clear about if both fields are required, and before rkt v0.8.1 if either field
was nil it would result in a crash.  Currently rkt will ignore isolators that don't have both fields set, so
I think this is a reasonable approach to making sure isolators are actually used.

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.
