bc8af553a3 Configure the kubelet to bind a simple healthz server to a localhost 
port for monitoring by monit. This is in preparation for the standard
kubelet port to switch to SSL only (and eventually to only accepting
connections on the SSL port that present a proper client SSL cert).

Also standardize the formatting of the monit config files a bit.

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.

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>`.

2ca265ae3b Remove --etcd_servers flag from kubelet and proxy. 
All the distros that use this have been updated,
or have PRs out to update them, or owners
have been asked to fix RPMs.

Removing this prevents further use of this model.

Remove now dead code: EtcdClientOrDie

Remove now dead pkg/proxy/config/etcd.go.

Remove unused imports.

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.

We want to sync pods from file/http/etcd sources to the apiserver, hence
differentiating sources is no longer desired.
