apiserver: cancel context on timeout in WithTimeoutForNonLongRunningRequests
Requests that block time out after 60sec, but keep the handler body running. This can lead to exhaustion of clients or other leaks. This PR adds a cancel func to the context of the request and calls it on timeout.
Note: we still do our own timeout handling as we don't trust the context to really cancel every blocking call we do.
This might explain why we see so many handler backtraces like https://gist.github.com/sttts/0ce972dc8a7911e4ca9eea7bf1ded5fa when an etcd node goes down with a hard poweroff. But it does not explain why we see oc to block for 15 minutes.

Prevent webhooks from affecting admission requests for WebhookConfiguration objects
**What this PR does / why we need it**:
As it stands now webhooks can be added to the system which make it impossible for a user to remove that webhook, or two webhooks could be registered which make it impossible to remove each other.
The first commit of this will add a test to make sure webhook deletion is never blocked by a webhook. This test will fail until the second commit is added which will prevent webhooks from affecting admission requests for ValidatingWebhookConfiguration and MutatingWebhookConfiguration objects in the admissionregistration.k8s.io group
- [x] Test that webhook deletion is never blocked by a webhook ([test fails before second commit](https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/pr-logs/pull/59840/pull-kubernetes-e2e-gce/23731/))
- [x] Prevent webhooks from being called on admission requests for [Validating|Mutating]WebhookConfiguration objects
- [x] Document this new behavior maybe in another PR

Remove dep-reviewers
**What this PR does / why we need it**:
The dep-reviewers group seems to get assigned PRs early the the review process. However, most code changes should be reviewed in the importing part of the code base first, and then assigned to an approver after.
By removing the reviewers group, the approvers plugin will still suggest assigning to an approver, but won't assign for review when the PR is initially opened.
**Release note**:
```release-note
NONE
```

code-gen: output golint compliant 'Generated by' comment
New PR instead of reopening #58115 because /reopen did not work.
This won't be ready to merge until the upstream https://github.com/kubernetes/gengo/pull/94 merges. Once that merges, the second commit will be changed to godep-save.sh and update-staging-godeps.sh, and the last commit will be changed to update-all.sh
The failing test is due to the upstream changes not being merged yet
```devel-release-note
Go code generated by the code generators will now have a comment which allows them to be easily identified by golint
```
Fixes#56489

Serve OpenAPI spec with single /openapi/v2 endpoint
**What this PR does / why we need it**:
We are deprecating format-separated endpoints (`/swagger.json`, `/swagger-2.0.0.json`, `/swagger-2.0.0.pb-v1`, `/swagger-2.0.0.pb-v1.gz`) for OpenAPI spec, and switching to a single `/openapi/v2` endpoint in Kubernetes 1.10. The design doc and deprecation process are tracked at: https://docs.google.com/document/d/19lEqE9lc4yHJ3WJAJxS_G7TcORIJXGHyq3wpwcH28nU
Requested format is specified by setting HTTP headers
header | possible values
-- | --
Accept | `application/json`, `application/com.github.proto-openapi.spec.v2@v1.0+protobuf`
Accept-Encoding | `gzip`
This PR changes dynamic_client (and kubectl as a result) to use the new endpoint. The old endpoints will remain in 1.10 and 1.11, and get removed in 1.12.

**Release note**:
```release-note
action required: Deprecate format-separated endpoints for OpenAPI spec. Please use single `/openapi/v2` endpoint instead.
