make private root dirs for integration test kubelets

Doc fixes

Remove user agent logging (doesn't add significant value)

We can reintroduce path/agent logging at a later point, this just clogs
verbose logs.

Kill the forced upload to GCS.

This actually tickles the -opipefail, and is only necessary if you're
rebuilding (which isn't really safe, because it can slice downstream
builds.)

chmod 755 hack/jenkins/build.sh (sorry)

Initial commit of Jenkins script + README

Reenable coverage and race detection on Travis

Fix flaky test.

And a config description. This doesn't yet have much - first want to
make sure I can do the build job. Next I'll submit the e2e script with
its twiddles and switch those over. (After going to 3 e2es, I think
it's finally time for version control.)

Maps are randomly reordered.
But there is only one order for one thing.

Remove go 1.2 from travis-ci

Update the doc on how to test for flakiness to actually work and to use kubectl.

Print PodIP along with Pod.Name for kubectl get pod <id>

Changes to improve swagger ui

This will be used to connect Reflector to kubelet update channel.

Fix error messages; add tests

Design doc for clustering.

- Separating out index, version and api handlers into independent web

  /version and the api handler to /api,
