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.

6881db64a9 Allow configurable Kubelet net image for isolated networks 
Public access to the DockerHub is not guaranteed in all environments,
add a flag to the kubelet that allows it to use a different image (like
one on a private registry) as well as only pull the first time the
image is needed.

Fixes #1545

0f97a73c1b Rename a bunch of "Make" functions to "New" 
Also rename some to other names that make better reading.  There are still a
bunch of "make" functions but they do things like assemble a string from parts
or build an array of things.  It seemed that "make" there seemed fine.  "New"
is for "constructors".

b131da1cf5 Sync pods asynchronously in the Kubelet. 
This makes two main changes:
- Runs syncPod in a separate Go routine (and enforces only one of those
  runs at a time).
- Uses the pod list to determine if a container should be running or
  should be killed (used to use the output of syncPod).

Since Docker pulls are synchronized by the Docker daemon we still block
on that, but pods can now be removed and prepared for starting without
blocking on long pulls.

7767c2a2ac Switch the Kubelet to use kubelet/config 
Also transfer the Kubelet from using ContainerManifest.ID to source specific
identifiers with namespacing.  Move goroutine behavior out of kubelet/ and
into integration.go and cmd/kubelet/kubelet.go for better isolation.

67efa0a53a Add test cases for Docker image name parsing and cleanup 
The tests for Docker image name parsing are repetitive and do not
cover enough test cases.

Refactor the tests to use table testing and add additional test cases.
