3a3b950009 Fix data race in imageManager test. 
The background monitoring thread was using the DockerClient before we
had written our fake data. This commit stops the background thread from
running during tests.

Fixes #5611.

d78ecf820e Garbage collecting images in the Kubelet. 
Integrated the imageManager into the Kubelet and applies the garbage
collection policy every 5 minutes. The default policy allows up to 90%
disk usage, after which images are garbage collected to bring limit back
down to 80%.

Fixes #157.

4c17c09a8f Separate GC policy into containerGC struct. 
The policy today takes a min GC age, max dead containers per pod, and
max containers overall. When GC is called, only dead containers created
more than min GC age ago are considered. The policy tries to keep one
dead instance of every pod's containers.

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>`.
