Fix etcd in proxy for namespace awareness
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.
Write BoundPods to etcd instead of ContainerManifestList

Rename ManifestFactory -> BoundPodFactory and change the general structure
of the call to focus on BoundPod.
Rename the etcd path for pods to be /registry/nodes/<>/boundpods
