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 ).

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.

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.

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.

Switch to glog for logging, bridge logging to glog.
...
1) imported glog to third_party (previous commit)
2) add support for third_party/update.sh to update just one pkg
3) search-and-replace:
s/log.Printf/glog.Infof/
s/log.Print/glog.Info/
s/log.Fatalf/glog.Fatalf/
s/log.Fatal/glog.Fatal/
4) convert glog.Info.*, err into glog.Error*
Adds some util interfaces to logging and calls them from each cmd, which
will set the default log output to write to glog. Pass glog-wrapped
Loggers to etcd for logging.
Log files will go to /tmp - we should probably follow this up with a
default log dir for each cmd.
The glog lib is sort of weak in that it only flushes every 30 seconds, so
we spin up our own flushing goroutine.
