change the relative links to definition in operations.html
...to satisfy the new directory layout in the kubernetes.io.
This will make the manual changes in https://github.com/kubernetes/kubernetes.github.io/pull/369 persist.
I still need to bump up the gcr.io/google_containers/gen-swagger-docs image version. I'll do that after I get LGTM here.

Node E2E: Make node e2e parallel
For https://github.com/kubernetes/kubernetes/issues/29081.
Fix https://github.com/kubernetes/kubernetes/issues/26215.
Based on https://github.com/kubernetes/kubernetes/pull/28807, https://github.com/kubernetes/kubernetes/pull/29020, will rebase after they are merged.
**Only the last commit is new.**
We are going to move more tests into the node e2e test. However, currently node e2e test only run sequentially, the test duration will increase quickly when we add more test.
This PR makes the node e2e test run in parallel so as to shorten test duration, so that we can add more test to improve the test coverage.
* If you run the test locally with `make test-e2e-node`, it will use `-p` ginkgo flag, which uses `(cores-1)` parallel test nodes by default.
* If you run the test remotely or in the Jenkin, the parallelism will be controlled by the environment variable `PARALLELISM`. The default value is `8`, which is reasonable for our test node (n1-standard-1).
Before this PR, it took **833.592s** to run all test on my desktop.
With this PR, it only takes **234.058s** to run.
The pull request node e2e run with this PR takes **232.327s**.
The pull request node e2e run for other PRs takes **673.810s**.

Adding GCI to node e2e.
Depends on https://github.com/kubernetes/kubernetes/pull/29486
Adding the dev release as of now since stable and beta run docker v1.9.1
which is incompatible with kubelet.

Fix 29451
Fix#29451. I've also checked other tests in that file to make sure they don't have similar problems.
The issue is P0 and will block the submit queue, so I marked this PR as P0.

pkg/various: plug leaky time.New{Timer,Ticker}s
According to the documentation for Go package time, `time.Ticker` and
`time.Timer` are uncollectable by garbage collector finalizers. They
leak until otherwise stopped. This commit ensures that all remaining
instances are stopped upon departure from their relative scopes.
Similar efforts were incrementally done in #29439 and #29114.
```release-note
* pkg/various: plugged various time.Ticker and time.Timer leaks.

Add rules for kube-scheduler
Just find that we have also missed the rule for `kube-scheduler`. I don't want to mix the rule with #29683 (make help) now. Will merge them finally if #29683 can be merged.

Update acquire to use newer JitterUntil vs. sleep
Fix to prevent https://github.com/kubernetes/kubernetes/issues/26782 which could have had a race on a 0 timer the way it was written before due to changes in wait.
I will likely make a PR for some of the recent changes in wait as well.

Remove redundant pod deletion in scheduler predicates tests and fix taints-tolerations e2e
~~In scheduler predicates test, some tests won't clean pods they created when exit with failure, which may lead to pod leak. This PR is to fix it.~~
Remove redundant pod deletion in scheduler predicates tests, since framework.AfterEach() already did the cleanup work after every test.
Also fix the test "validates that taints-tolerations is respected if not matching", refer to the change on taint-toleration test in #29003, and https://github.com/kubernetes/kubernetes/pull/24134#discussion_r63794924.

Initial support for pod eviction based on disk
This PR adds the following:
1. node reports disk pressure condition based on configured thresholds
1. scheduler does not place pods on nodes reporting disk pressure
1. kubelet will not admit any pod when it reports disk pressure
1. kubelet ranks pods for eviction when low on disk
1. kubelet evicts greediest pod
Follow-on PRs will need to handle:
1. integrate with new image gc PR (https://github.com/kubernetes/kubernetes/pull/27199)
1. container gc policy should always run (will not be launched from eviction, tbd who does that)
1. this means kill pod is fine for all eviction code paths since container gc will remove dead container
1. min reclaim support will just poll summary provider (derek will do follow-on)
1. need to know if imagefs is same device as rootfs from summary (derek follow-on)

Check iscsi iface file for transport name
When checking for tcp vs hardware transports, check actual iscsi iface file to see if we are using tcp as a transport, rather than relying on just the transport name of 'default'.
This fixes the open-iscsi software iscsi initiator for non-default interfaces.

remove the omitempty tag from CertificateSigningRequestList.Items
As a general rule, `Items` should be a required field in all lists. In a followup PR, I'll update the api-convention.md and add a check in the schema registration path to enforce the rule. I need to fix this bug to unblock other work.

Add a docker-shim package
Add a new docker integration with kubelet using the new runtime API.
This change adds the package with the skeleton and implements some of the basic operations.
This PR only implements a small sets of functions. The rest of the functions will be implemented
in the followup PRs to keep the changes readable, and the reviewers sane.
Note: The first commit is from #28396, only the second commit is for review.

Bump exechealthz image
With the new image at least if we observe an exec container taking more ram than it should (like the oom situation, which shouldn't happen today because of the increased limits), we can kubectl exec and check the pprof endpoints.
Note that I'm not bumping the rc version, because I just did so with: https://github.com/kubernetes/kubernetes/pull/29693.

Add support for GCI QA jobs
GCI QA jobs will run tests using GCI daily builds, and the kubernetes built into
the images. All QA jobs will set the `JENKINS_USE_GCI_VERSION` env var.
