2a0d7ebb11 Add support for pluggable Docker exec handlers
Add support for pluggable Docker exec handlers. The default handler is
now Docker's native exec API call. The previous default, nsenter, can be
selected by passing --docker-exec-handler=nsenter when starting the
kubelet.

2cf0dfb79d Handle out of disk situation on kubelets.
Kubelet will stop accepting new pods if it detects low disk space on root fs or fs holding docker images.
Running pods are not affected. low-diskspace-threshold-mb is used to configure the low diskspace threshold.

d78ecf820e Garbage collecting images in the Kubelet.
Integrated the imageManager into the Kubelet and applies the garbage

down to 80%.

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>`.

ab3c9de34b Refactoring cAdvisor interface into a package.
This will make it easier to start running the real cAdvisor alongside
Kubelet. This change is primarily no-op refactoring. The main behavioral
change is that we always create a cAdvisor interface and expect it to
always be available. When we make a request, if cAdvisor is not
connected the request fails with a connection error. This failure is
handled today as well.
