Tim St. Clair 368447ff3f Rector kubelet stats serving 
Changes include:
- Moving stats serving & routes to pkg/kubelet/server/stats/handler.go
- Managing the routes with restful.WebService, rather than manual
parsing
- Misc cleanup

These changes will make adding the new routes for /stats/summary more
manageable.

Tim St. Clair 89bc7992f9 Refactor kubelet server into its own package 
Refactor Kubelet's server functionality into a server package. Most
notably, move pkg/kubelet/server.go into
pkg/kubelet/server/server.go. This will lead to better separation of
concerns and a more readable code hierarchy.

Yu-Ju Hong 0b8244505c Add a slow e2e test to monitor kubelet resource usage 
This test tracks kubelet resource usage over a long period of time (1hr)
when running N pods (e.g., N=0,50), and prints out the resource usage. This
would give us an idea how much kubelet's management overhead is in a stable
cluster.

Some followup items:
 * Use a more realistic workload (e.g., including probing)
 * Fail the test if the resource usage is too high.

Caveat:
 * We assume the scheduler would do a decent job distributing the pause pods,
   but we should double check.
 * Cluster addon pods could be unevenly distributed and skews the resource
   usage on nodes.

Yu-Ju Hong ab85b9a7d6 e2e: add a function to reset the stats in resource monitor 
The function can be called in a long-running test to clear exsiting
stats (free the memory), and start over.

Dr. Stefan Schimanski 643a7f193a Assume full cgroup hierarchy only on gce and gke for e2e tests 
Other cluster provider than gce or gke might have different cgroup layouts.
From outside we cannot know how these look like (especially in conformance test
which do not know the cluster provider at all).

Hence, this PR defaults to only the "/" cgroup to collect stats for. In the case
of gce or gke the full container list is tested.

tummychow 78ce5da988 Move util.StringSet into its own package 
A lot of packages use StringSet, but they don't use anything else from
the util package. Moving StringSet into another package will shrink
their dependency trees significantly.

Yu-Ju Hong 12a252bd8b e2e: add resourceMontior to poll resource usages on the nodes 
This change adds resourceMontior, which spawns a goroutine per node to poll the
container stats for known, relevant containers, computes the resource usage and
stores the data. Users can then examine the data in the buffer to get resource
of each individual containers.

Yu-Ju Hong 378a44a287 e2e: query kubelet for resource usage of containers 
This change adds simple utility functions to query kubelet for the resource
usage of major containers (e.g. /kubelet, /docker-daemon, etc) for the past
time interval (up to 2 minutes). This is intended for spot checking of the
recent resource usage on the node.

Yu-Ju Hong a10a6a296e Add an e2e test to verify that pods are deleted on nodes 
The test verifies that kubelet deletes the pods/containers within a reasonable
time. It queries the kubelet /runningpods endpoint to retrieve a list of
running pods directly. The outline of the test is:

 - Create an RC
 - Wait until all pods are running (based on the pod status)
 - Verify pods are running by querying the /runningpods
 - Delete the RC
 - Check all pods are deleted by querying /runningpods
