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.
