d81ecc58f8 Adapt pod killing and cleanup for generic container runtime 
This change removes docker-specifc code in killUnwantedPods. It
also instructs the cleanup code to move away from interacting with
containers directly. They should always deal with the pod-level
abstraction if at all possible.

called later in the SyncPods() sequence, which should remove these pod
directories.

6b0db76e85 Move killPod() logic to DockerManager KillPod(). 
This moved Docker specific logic there and allows it to align with the
runtime API. There is still a pod infra container reference in the
function due to network plugins. We can handle this in the Kubelet since
we'll need to be explicit in stating that the network plugin will not
work in a non-Docker runtime.

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.

275002173e Kubelet: parallelize cleaning up containers in unwanted pods 
Kubelet kills unwanted pods in SyncPods, which directly impact the latency of a
sync iteration. This change parallelizes the cleanup to lessen the effect.

Eventually, we should leverage per-pod workers for cleanup, with the exception
of truly orphaned pods.

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.

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().

929fb63b33 Sync static pods from Kubelet to the API server 
Currently, API server is not aware of the static pods (manifests from
sources other than the API server, e.g. file and http) at all. This is
inconvenient since users cannot check the static pods through kubectl.
It is also sub-optimal because scheduler is unaware of the resource
consumption by these static pods on the node.

This change syncs the information back to the API server by creating a
mirror pod via API server for each static pod.

 - Kubelet creates containers for the static pod, as it would do
   normally.

 - If a mirror pod gets deleted, Kubelet will re-create one. The
   containers are sync'd to the static pods, so they will not be
   affected.

 - If a static pod gets removed from the source (e.g. manifest file
   removed from the directory), the orphaned mirror pod will be deleted.

Note that because events are associated with UID, and the mirror pod has
a different UID than the original static pod, the events will not be
shown for the mirror pod when running `kubectl describe pod
<mirror_pod>`.

fe70be9261 kubelet: revamp the pod/container naming scheme 
There are two main goals for this change.

 1. Fix the naming scheme in kubelet so that it accepts DNS subdomain
    name/namespaces correctly (#4920). The design is discussed in #3453.

 2. Prepare for syncing the static pods back to the apiserver(#4090). This
    includes

  - Eliminate the source component in the internal full pod name (#4922). Pods
    no longer need sources as they will all be sync'd via apiserver.

  - Changing the naming scheme for the static (file-, http-, and etcd-based)
    pods such that they are distinguishable when syncing back to the apiserver.

The changes includes:
  *	name = <pod.Name>-<hostname>
  * namespace = <cluster_namespace> (i.e. "default" for now).
  * container_name = k8s_<contianer_name>.<hash_of_container>_<pod_name>_<namespace>_<uid>_<random>

Note that this is not backward-compatible, meaning the kubelet won't recognize
existing running containers using the old naming scheme.

3ccdb8db98 kubelet: reject pods on host port conflict 
When a host port conflict is detected, kubelet should set the pod status to
fail. The failed status will then be polled by other components at a later time,
which allows replication controller to create a new pod if necessary.

To achieve this, this change stores the pod status information in a status map
upon the detecton of port conflict. GetPodStatus() consults this status map
before attempting to query docker. The entries in the status map will be removed
when the pod is no longer associated with the node.
