Make POD container last OOM victim.
...
Setting the oom_score_adj of the PID of the POD container to -100 which is less
than the default of 0. This ensures that this PID is the last OOM victim
chosen by the kernel.

Use Docker name (not ID) to parse Kubernetes components.

Since the parsing function doesn't return an error all the components
returned empty strings. This caused us to enforce the MaxContainerLimit
as a global limit instead of a per-container limit.

Kublet watches Pods.
...
Added a kubelet config source for watching pods on apiserver.
The pods are converted to boundpods for merging with other
config sources.
The preferred way to create a kubelet is now to pass an apiserver
client but not an etcd client. Changed cmd/integration to use
apiserver to talk to kubelets. And cmd/kubernetes.
Unit, integration, and e2e tests pass, except for a failure of the pd
e2e test which was unrelated.

Avoid race between image pull and garbage collect
...
Hold the pullLock while pulling regular container images, not just the
network container.
Also: previously, the locks were grabbed at too-low a layer in the
callstack, leaving a (narrow) window where images could be pulled and
then garbage collected before being used.
This change takes the existing pullLock a layer higher in the call stack
so the critical regions encompass the entire find+delete and pull+use
operation in both cases.
