e6820bd0ca kubelet_test: Fix verifyStringArrayEqualsAnyOrder(). 
Old implementation can not tell cases where strings are
repetitive. e.g. {"a", "b", "b"} and {"a", "a", "b"} will
be treated as correct.

aa2e7fe688 kubelet_test: Add verifyUnorderedCalls(). 
This fixes TestSyncPodsDeletesWithNoPodInfraContainer.
Since we need to sync two pods in parallel, we should not verify
the docker calls in strict order.

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.

f440989017 Kubelet: add podManager for managing internal pod storage 
This change moves pod array and mirrorPods into podManager, along with all
methods accessing these internal pod storages. This is the first step of the
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.

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>`.
