80e799fc0c Allow configuring the rkt binary in a kubelet with a flag. 
This is necessary because coreos comes with rkt installed, and if we want to use a different version
we need some way to avoid the default one.

0c84b837cf kubelet: switch to using pod UID as the key in status manager 
We chose to use podFullName (name_namespace) as key in the status manager
because mirror pod and static pod share the same status. This is no longer
needed because we do not store statuses for static pods anymore (we only
store statuses for their mirror pods). Also, reviously, a few fixes were
merged to ensure statuses are cleaned up so that a new pod with the same
name would not resuse an old status.

This change cleans up the code by using UID as key so that the code would
become less brittle.

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.

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.

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.

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.
