bb417e82d7 Kubelet: surface the container creation/start failure reason 
Container creation/start failure cannot be reproduced by inspecting the
containers. This change caches such errors so that kubelet can retrieve it
later.

This change also extends FakeDockerClient to support setting error response
for a specific function.

If a static pod changes, delete the corresponding mirror pod. When kubelet
could not see mirror pod from the API server update, it'd attemp to create a
new mirror pod with up-to-date specs.

d01bc660b5 Kubelet: a step towards to better encapsulation of docker functions 
We want to stop leaking more docker details into kubelet, and we also want to
consolidate some of the existing docker interfaces/structs. This change creates
DockerManager as the new home of some functions in dockertools/docker.go. It
also absorbs containerRunner. In addition, GetDockerPodStatus is renamed to
GetPodStatus with the entire pod passed to it so that it is simialr to the what
is defined in the container Runtime interface.

Eventually, DockerManager should implement the container Runtime interface, and
integrate DockerCache with a flag to turn on/off caching. Code in kubelet.go
should not be using docker client directly.

08e4a883b6 Kubelet: refactor pod manager 
This change cleans up the pod manager extensively so that
 * Mirror pods are actually stored in the pod manager.
 * Both (non-mirror) pods and mirror pods are indexed by UID and full name for
   easy lookup and mapping. This is required for the next change to send
   full pod along with the pod status update.

This change also renames mirrorManager as mirrorClient since it is merely a
client to contact the API server and create/delete mirror pods.

15e9760bd4 Kubelet: support retrieving stats using UID of mirror pod 
Kubelet supports retrieving stats for pods/containers with and without UID.
This does not always work for the static pods because users may get the UIDs of
the mirror pods from the API server, and use them to query Kubelet. In this
case, Kubelet would fail to locate the containers due to mismatched UIDs.

This change adds a intenral mirror to static pod UID mapping and teaches all
public-facing functions to perform UID lookup before proceeding. This allows
users to use either mirror or static pod's UID to retrieve stats.

0d0fb5f07b Kubelet: per-pod workers should avoid grabbing the pod array lock 
Per-pod worker syncs the pod and container status, and write the pod status in
the pod status cache. Given that it already owns a copy of the pod, it can
bypass the additional pod lookup step completely. This change adds a new
generatePodStatusByPod() method to achieve this. In general, per-pod worker
should avoid accessing the internal pod array completely, as this would may
lead to high contention.

This change also changes the return type of GetPodByFullName to reflect the
name, and consolidates GetPodByFullName() and GetPodByName().
