8e7d14196f Fix printing errors from failed binary runs
I had the kublet die on startup and the only error was "0x401da0"  Which
I assume is an address of the err.Error function.  The other way to fix
this, I think, would be to use err.Error(), however that could cause
fmt.Fprintf() problems, debuging on the error message people used.

Now I get a nice clean error I can understand:

"cAdvisor.New() err = mountpoint for cpu not found"

76df5471b5 Covert the kubelet binary to hyperkube.
This leaves `pkg/kubelet/server/server.go` looking a little ugly as there is an extra layer of "config" structs that isn't needed.  This is left as a TODO for now.

6cb275829f Implement volumes as plugins.
Break up the monolithic volumes code in kubelet into very small individual
modules with a well-defined interface.  Move them all into their own packages
and beef up testing along the way.

b759f67ee3 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.

652479a3b1 Add kubelet DNS flags & api disable for DNS
This adds --cluster_dns and --cluster_domain flags to kubelet.  If
non-empty, kubelet will set docker --dns and --dns-search flags based on
these.  It uses the cluster DNS and appends the hosts's DNS servers.
Likewise for DNS search domains.

This also adds API support to bypass cluster DNS entirely, needed to
bootstrap DNS.

1d8067450c Rename pkg/version/flag to pkg/version/verflag
This avoids some conflict with the built-in `flag` module in Go. The
module was already being renamed to `verflag` on import anyways, so we
might as well just call it that.

Tested:
- hack/build-go.sh and ran the resulting binaries with -version args.

331fd0d986 Extract "pkg/version".PrintAndExitIfRequested() to its own package
because it causes a runtime panic if a binary which has its own implementation
of "-version" flag tries to reuse a package library which indirectly depend on
"pkg/version".

e.g. If such an user-defined binary tires to link "pkg/api" or "pkg/client",
the binary fails with a runtime panic "flag redefined: version".

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.

9f9e75f508 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.
