docs:examples:guestbook: don't advice untagged image
Using untagged images means no version at all, this can cause weird problems.
Right now, `redis:latest` is no longer compatible with the redis version used in the slave service of the example.

Uses container/heap for DelayingQueue
The current implementation of DelayingQueue doesn't perform very well when a large number of items (at random delays) are inserted. The original authors seemed to be aware of this and noted it in a `TODO` comment. This is my attempt at switching the implementation to use a priority queue based on `container/heap`.
Benchmarks from before the change:
```
╰─ go test -bench=. -benchmem | tee /tmp/before.txt
BenchmarkDelayingQueue_AddAfter-8 300000 256824 ns/op 520 B/op 3 allocs/op
PASS
ok k8s.io/kubernetes/staging/src/k8s.io/client-go/util/workqueue 77.237s
```
After:
```
╰─ go test -bench=. -benchmem | tee /tmp/after.txt
BenchmarkDelayingQueue_AddAfter-8 500000 3519 ns/op 406 B/op 4 allocs/op
PASS
ok k8s.io/kubernetes/staging/src/k8s.io/client-go/util/workqueue 2.969s
```
Comparison:
```
╰─ benchcmp /tmp/before.txt /tmp/after.txt
benchmark old ns/op new ns/op delta
BenchmarkDelayingQueue_AddAfter-8 256824 3519 -98.63%
benchmark old allocs new allocs delta
BenchmarkDelayingQueue_AddAfter-8 3 4 +33.33%
benchmark old bytes new bytes delta
BenchmarkDelayingQueue_AddAfter-8 520 406 -21.92%
```
I also find the `container/heap`-based code a bit more easy to understand. The implementation of the PriorityQueue is based on the documentation for `container/heap`.
Feedback definitely welcomed. This is one of my first contributions.

kube-apiextensions-server: Fix potential SEGV with null delegate handler
**What this PR does / why we need it**:
In the kube-apiextensions-server there is a fallback value for `null` delegate to `http.NotFoundHandler()` in handling group and versions discovery, but no fallback for custom resources endpoint.
It leads to SEGV when running with `genericapiserver.EmptyDelegate`.

Fix discovery version for autoscaling to be v1
The order of the storage setup blocks in the setup for the autoscaling
API group was accidentally inverted, meaning that if the v2alpha1 API
group was turned on, it would be set to the preferred API group-version
for discovery.
This was unintentional; the latest stable version should (v1) should be
preferred instead.
**Release note**:
```release-note
Ensure that autoscaling/v1 is the preferred version for API discovery when autoscaling/v2alpha1 is enabled.

[Federation] Fix federated service reconcilation issue due to addition of External…
…TrafficPolicy field to v1.Service
**What this PR does / why we need it**:
New fields (ExternalTrafficPolicy) are introduced to v1.Service by this PR #41162. If this field is not specified in service spec, the service controller will assign default and updates the service spec.
In federation, the service spec is not updated and we continuously try to reconcile as the federated service and the service in federated cluster do not match.

Allow certificate manager to be initialized with client.
Add test coverage to the certificate manager covering the initialization
scenario where it is initialized with no Certificate Request Signing
client, then the client is added later. This matches how it will be used
when the Certificate Request Signing client is also the consumer of the
certificate manager.

Reorganize kubelet tree so apis can be independently versioned
@yujuhong @lavalamp @thockin @bgrant0607
This is an example of how we might reorganize `pkg/kubelet` so the apis it exposes can be independently versioned. This would also provide a logical place to put the `KubeletConfiguration` type, which currently lives in `pkg/apis/componentconfig`; it could live in e.g. `pkg/kubelet/apis/config` instead.
Take a look when you have a chance and let me know what you think. The most significant change in this PR is reorganizing `pkg/kubelet/api` to `pkg/kubelet/apis`, the rest is pretty much updating import paths and `BUILD` files.

Limiting client go packages visibility, round 3
Continue the work in the merged PR https://github.com/kubernetes/kubernetes/pull/45258
These packages in client-go will be gone after #44065 is fixed:
pkg/api/helper, pkg/api/util, internal version of api groups, API install packages.
This PR removes the dependency on these packages and add bazel visibility rules to prevent relapse.

Promotes Source IP preservation for Virtual IPs from Beta to GA
Fixes#33625. Feature issue: kubernetes/features#27.
Bullet points:
- Declare 2 fields (ExternalTraffic and HealthCheckNodePort) that mirror the ESIPP annotations.
- ESIPP alpha annotations will be ignored.
- Existing ESIPP beta annotations will still be fully supported.
- Allow promoting beta annotations to first class fields or reversely.
- Disallow setting invalid ExternalTraffic and HealthCheckNodePort on services. Default ExternalTraffic field for nodePort or loadBalancer type service to "Global" if not set.
**Release note**:
```release-note
Promotes Source IP preservation for Virtual IPs to GA.
Two api fields are defined correspondingly:
- Service.Spec.ExternalTrafficPolicy <- 'service.beta.kubernetes.io/external-traffic' annotation.
- Service.Spec.HealthCheckNodePort <- 'service.beta.kubernetes.io/healthcheck-nodeport' annotation.

Don't attempt to make and chmod subPath if it already exists
fixes https://github.com/kubernetes/kubernetes/issues/45613https://github.com/kubernetes/kubernetes/pull/43775 fixed one bug and introduced another... I overlooked that subPaths can be files, in which case MkDirAll will simply fail and the pod will not able to start.
Regardless of whether it is a directory or a file, there is no need to introduce the MkdirAll->Chmod procedure if it exists, because if it exists, it should already have the correct permissions.
This needs to be cherry-picked into 1.6.

Remove a test utility function that is redundant and kinda broken
Framework.WaitForAnEndpoint() has no timeout, so if something goes wrong and the endpoint doesn't get created, the test will hang forever. (This is happening for some reason sometimes in OpenShift right now, and when the CI system eventually times out and kills the VM, it loses the logs that would explain what failed.)
There's already another nearly-identical WaitForEndpoint() method that *does* take a timeout, so people can just use that instead.
