79fc8bee34 Change GetContainerLogs() signature.

Kubelet: replace DockerManager with the Runtime interface

1ad4dd7803 Kubelet: replace DockerManager with the Runtime interface 
This change instructs kubelet to switch to using the Runtime interface. In order
to do it, the change moves the Prober instantiation to DockerManager.

Note that most of the tests in kubelet_test.go needs to be migrated to
dockertools. For now, we use type assertion to convert the Runtime interface to
DockerManager in most tests.

4fe3366b04 Removes RunPod in the Runtime interface 
SyncPod subsumes RunPod, so the latter is no longer needed.
After this change, DockerManager implements the Runtime interface.

Victor Marmol
3b9eba2c1b Add SyncPod() to DockerManager and use in Kubelet. 
This allows us to abstract away the logic of syncing a pod by the
runtime. It will allow other runtimes to perform their own sync as well.

6316b485ad Add SyncPod() and remove Kill/Run InContainer(). 
SyncPod allows us to abstract away how a pod is started and updated. It
also simplifies what the runtime has to implement.

Kubelet: filter out terminated pods in SyncPods

b0e6926f67 kubelet: filter out terminated pods in SyncPods 
Once a pod reaches a terminated state (whether failed or succeeded), it should
not transit out ever again. Currently, kubelet relies on examining the dead
containers to verify that the container has already been run. This is fine
in most cases, but if the dead containers were garbage collected, kubelet may
falsely concluded that the pod has never been run. It would then try to restart
all the containers.

This change eliminates most of such possibilities by pre-filtering out the pods
in the final states before sending updates to per-pod workers.

06125f37d3 Print container statuses in kubectl get pods 
`kubectl get pod` already prints one container per line. This change fills in
the status for each container listed. This aims to help users quickly identify
unhealthy pods (e.g. in a crash loop) at a glance.

 - The first row of every pod would display the pod information and status
 - Each row of the subsequent rows corresponds to a container in that pod:
    * STATUS refers to the container status (Running, Waiting, Terminated).
    * CREATED refers to the elapsed time since the last start time of the
      container.
    * MESSAGE is a string which explains the last termination reason, and/or
      the reason behind the waiting status.

fd34441d2d Kubelet: persist restart count of a container 
Currently, restart count are generated by examine dead docker containers, which
are subject to background garbage collection. Therefore, the restart count is
capped at 5 and can decrement if GC happens.

This change leverages the container statuses recorded in the pod status as a
reference point. If a container finished after the last observation, restart
count is incremented on top of the last observed count. If container is created
after last observation, but GC'd before the current observation time, kubelet
would not be aware of the existence of such a container, and would not increase
the restart count accordingly. However, the chance of this should be low, given
that pod statuses are reported frequently. Also, the restart cound would still
be increasing monotonically (with the exception of container insepct error).

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.

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.

refactoring, and no function change is involved.

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().
