2a345ffa9e third_party: update go-dockerclient 
math.MaxInt64 represents 8 exabytes, which is a good limit for memory.
Also, this is the type used by Docker, so it's not possible to get any
value bigger than math.MaxInt64 as memory limit (both ram and swap) on a
Docker container.

Relevant discussion at #589 (more precisely,
https://github.com/GoogleCloudPlatform/kubernetes/pull/589#issuecomment-50640605).

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.

procedures. Currently used for volume mounts.

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.

88317efb42 Add a pause image for the net container. 
The pause image is a 240KB image that simply pauses waiting on a signal.
Use this for the net container which only needs to act as a placeholder.
Current net image is ~2.5MB. From my tests, this reduces startup time
for the net container from ~14s to ~6s.

dc7ee7c333 normalize -etcd_servers flag across all commands 
The -etcd_servers flag is used inconsistently by the Kubernetes commands,
both externally and internally.

This patch fixes the issue by using the same type to represent a list of
etcd servers internally, and declares the -etcd_servers flag consistently
across all commands.

This patch should be 100% backwards compatible with no changes in behavior.

3a95572290 Changed the keepChannel to buffered channel. 
Since the keepChannel is used to send data, not just for synchronizaiton,
so make it a buffered channel can avoid unnecessary goroutine yields.
