Automatic merge from submit-queue

Add some more info to the Jenkins README.

This is a bit of a work-in-progress, and I'd appreciate feedback on what to add or remove. I'm not sure that I need to say so much about the GCS format, and I should probably say some more about JJB.

Use tagged gcr.io redis image for pkg/api tests

Migrate pkg/api/validation/testdata redis images to use tagged gcr.io version for https://github.com/kubernetes/kubernetes/issues/13288 and https://github.com/kubernetes/kubernetes/issues/20836

Removing call to update-swagger-spec.sh from update-generated-swagger-docs.sh

Fixes https://github.com/kubernetes/kubernetes/issues/24233

Right now `update-generated-swagger-docs.sh` calls `update-swagger-spec.sh`, but `verify-generated-swagger-docs.sh` does not verify swagger spec (that is done by `verify-swagger-spec.sh`).
Hence, `verify-swagger-spec` breaks if it is called after `verify-generated-swagger-docs`.

Fixing it by removing the call to `update-swagger-spec.sh` from `update-generated-swagger-docs.sh`.
This will require users to run both `update-swagger-spec` and `update-generated-swagger-docs` when they update api types, but they already need to run many more scripts (`update-api-reference-docs`, `update-codegen`). 
People should mostly be running hack/update-all.sh directly :)

Shorten cluster names in GKE Jenkins on Trusty

We identified an issue that the PD tests in GKE Jenkins on Trusty fail because the PD name is longer than the limit of 63 characters. The PD name embeds the "E2E_NAME" env variable exported in the Jenkins job configuration. This PR shortens that string for all GKE Jenkins on Trusty. As a result, the PD name will meet the limit requirement.

Remove double assignment of KUBE_ROOT

`KUBE_ROOT` got assigned twice in the codegen script.

Fix goroutine leak in ssh-tunnel healthcheck.

Tunnel healthchecks were not closing the HTTP response body, leading to many open goroutines.

Bump kubernetes-test-go timeout.

It looks like the run times got more inconsistent because of load on the VM. Adding another Jenkins slave improved things so we're not constantly timing out, but it still gets a little close to timing out at times.

Average runtime is ~45 mins so I went with a 100 min timeout.

Fixes #24285

Remove soak and disruptive 1.1 Jenkins jobs.

They're both in the kubernetes-jenkins project, not their own. The disruptive one isn't a critical build, and I don't think the soak should be critical at all, since it's never green for a week anyway and I don't think we ever plan for it to be.

Client-gen: Add fake clients to testoutput; fix the imports in fake clients

Start generating fake client in the testoutput, so that we can check the fake client is generated correctly under extreme conditions.

Fix the problem reported https://github.com/kubernetes/kubernetes/pull/20573#issuecomment-210556618, where the import names contain dots when the group name contains dots.

Fix gce.getDiskByNameUnknownZone logic.

This should fix tag-pinned GKE tests that are currently broken
because #24058 doesn't exist for v1.2.2.

Bump upgrade test timout to 10 hours

@spxtr is it reasonable to expect that running the v1.2 tests in serial would take longer than ~ 5 hours (assuming the upgrade beforehand takes < 1 hour)?

Improve script for running scheduler benchmarks

Without this change, this script didn't work in my environment - it's making more consistent with other scripts.

Update API change for internal types

Clarify api-group docs by a tiny bit.

I realize this area is in flux and the doc is out of date, but it's strictly better with this update than without?

Use 3 nodes per zone in the GKE multizone test instead of 1

Automatic merge from submit-queue

Run test-go less often on release branches.

I made 1.2 run every 3 hours and 1.1 run every 6 hours. They'll still run right away once a build completes.

I'm going to have to lower the number of executors on the Jenkins slaves that run test-go jobs, since running 3 at a time makes them use up all the CPU and flake.

Replace tab with eight spaces

ThirdPartyResourceCodec should implement streaming.Framer

Wrappers must proxy NewFrameReader|Writer for now (until we potentially
refactor the codec factory to separate them).
