Chris Alfonso 1a45e37d17 NFSMount storage plugin for kubelet. 
* If you want to test this out when an actual NFS export a good place
 to start is by running the NFS server in a container:

docker run -d --name nfs --privileged cpuguy83/nfs-server /tmp

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

disk usage, after which images are garbage collected to bring limit back
down to 80%.

Victor Marmol 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.

Yu-Ju Hong 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>`.

Victor Marmol 51122998e3 Garbage collect unidentified Kubernetes containers. 
These containers may be caused by a change in the Kubernetes naming
convention. The old containers are killed, the new ones started, but the
old ones are never GC'd. This change makes Kubelet GC all Kubernetes
containers, old and new.

Victor Marmol 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.

Victor Marmol ca84aae454 Kubelet: wait up to 5m for Docker to come up. 
The Kubelet assumes Docker is running during its execution and on

Docker. This PR waits for Docker to be up before the Kubelet begins
doing useful work. On timeout, Kubelet exits and expects to be
restarted.

Yu-Ju Hong 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.

Yu-Ju Hong 32fd331e73 Revert "Split up kubelet "source seen" logic"

differentiating sources is no longer desired.

Victor Marmol 4f3f073f3c Implementing ImageManager to take over image lifecycle. 
All images are tracked, when they were created and when they were last
used. FreeSpace() evicts these images in least recently used order,
breaking ties with oldest first.

Yu-Ju Hong 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.

Yu-Ju Hong 241df2d3be kubelet: record an event with a clear reason on host port conflict 
Currently, kubelet silently ignores pods that caused host port conflict. This
commit surfaces the error by recording an event.

It also makes sure that kubelet iterates through the pods in the order of the
creation timestamp, which ensures that pods created later are ignored on
conflict.
