a35f4374c5 Update cAdvisor ContainerInfo references to v1 API. 
The cAdvisor data structures were versioned recently. We use the v1
versions so this commit makes that explicit.

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.

6d31c2bf8a util.EncodeJSON proven harmful, remove it everywhere 
People were misusing EncodeJSON in tests when they should be using
runtime.EncodeOrDie(testapi.Codec(), obj).  Removing the potential
for cutting self on sharp objects.

892942af8f Read BoundPods from etcd instead of ContainerManifestList 
There are three values that uniquely identify a pod on a host -
the configuration source (etcd, file, http), the pod name, and the
pod namespace. This change ensures that configuration properly
makes those names unique by changing podFullName to contain both
name (currently ID in v1beta1, Name in v1beta3) and namespace.

The Kubelet does not properly handle information requests for
pods not in the default namespace at this time.

300c2c5f6f Fix an issue on GetContainerInfo. 
I believe the issue was first introduced when we append namespace to docker
container's name. This is a temporary fix for #160.
