Adding static swagger spec and a script to update it

E2e services 4162

fixes kube-apiserver failure when using  aws/cloudformation-template.json

Breakfix for #4177, not a real solution

Typo

Revert jenkins/e2e.sh back to 606b517a, minus -tap

an else statement.  #4162

Check Docker version in Kubelet /healthz handler

Add more logging

inserted mising = in kube-apiserver's portal_net parameter that prevented the kube-apiserver from starting

Fix jenkins/hack/e2e.sh, log errors better

Pervert e2e shell tests to run under Ginkgo

To fix this, it would be an alias for:

  hack/ginkgo-e2e.sh -t TestNetwork

... which may not work on binary distributions, because it's relying
on test assets, so it probably shouldn't live in cluster/ ...

* Add a test/e2e/shell.go that slurps up everything in hack/e2e-suite
and runs it as a bash test, borrowing all the code from hack/e2e.go.

* Rip out all the crap in hack/e2e.go that deal with multiple tests

* Move hack/e2e-suite/goe2e.sh to hack/ginkgo-e2e.sh so that it
doesn't get slurped up.

contrib: add git-sync container

Clarify commenting in endpoints_controller

Make the replication controller more resilient to event expiration in watch.

kubectl proxy: make static prefix configurable

Fix tests in validation_test

Deleting the API objects related to /operations

Remove kubecfg from all getting started docs.

Make e2e shell tests work standalone

Simply incorporate some of the boilerplate from hack/e2e.go into the
scripts in hack/e2e-suite.

Use environment variables with default values to allow overrides in
kubectl command line and to use a versioned package root.

Tested:
- Ran `go run hack/e2e.go -test` on a test cluster.
- Ran the test cases individually.
- Ran hack/e2e-suite/goe2e.sh -t Pods to confirm it takes arguments.
- Also fixed cluster/test-network.sh (which should be more and more irrelevant.)
