This fix is linked to the PR #51153 that introduce the
JobSpec.BackoffLimit.
Previously the Timeout used in the test was too agressive and generates
flaky test execution. Now it used the default framework.JobTimeout used
in others tests.
This implements stats for windows nodes in a new package, winstats.
WinStats exports methods to get cadvisor like datastructures, however
with windows specific metrics. WinStats only gets node level metrics and
information, container stats will go via the CRI. This enables the
use of the summary api to get metrics for windows nodes.
This commit adds an option for controlling request of compaction to
etcd3 from apiserver. There is a situation that apiserver cannot fully
own its etcd cluster (e.g. sharing it with canal). In such a case,
apiserver should have limited access in terms of etcd's auth
functionality so it don't have a priviledge to issue compaction
requests. It means that the compaction requests should be issued by
other component and apiserver's compaction requests are needless.
For such use cases, this commit adds a new flag
`storagebackend.Config.CompactionInterval`. If the flag is non 0,
apiserver issues the compaction requests like current behaviour (the
default is 5 minutes). If it is 0, apiserver doesn't issue the
requests. It can be configured with a newly added option of apiserver
`--etcd-compaction-interval`.

Improve kubeadm help text
* Replace 'misc' with more specific at-mentions bugs and feature-requests.
* Replace ReplicaSets with Deployments as example, because ReplicaSets are dated.
* Generalize join example.
Before:

┌──────────────────────────────────────────────────────────┐
│ KUBEADM IS BETA, DO NOT USE IT FOR PRODUCTION CLUSTERS! │
│ │
│ But, please try it out! Give us feedback at: │
│ https://github.com/kubernetes/kubeadm/issues │
│ and at-mention @kubernetes/sig-cluster-lifecycle-misc │
└──────────────────────────────────────────────────────────┘
Example usage:
Create a two-machine cluster with one master (which controls the cluster),
and one node (where your workloads, like Pods and ReplicaSets run).
┌──────────────────────────────────────────────────────────┐
│ On the first machine │
├──────────────────────────────────────────────────────────┤
│ master# kubeadm init │
└──────────────────────────────────────────────────────────┘
┌──────────────────────────────────────────────────────────┐
│ On the second machine │
├──────────────────────────────────────────────────────────┤
│ node# kubeadm join --token=<token> <ip-of-master>:<port> │
└──────────────────────────────────────────────────────────┘
You can then repeat the second step on as many other machines as you like.

Minor fixes to validation test
Some test cases confuse the new object with the old object. This PR fixed that. Also added a test to verify that deletionTimestamp cannot be added (via the REST endpoints).
Fix#49256
When `ScalingLimited = true` for the `hpa`, there is an accompanying
status message, describing why scaling is limited. Previously if the desired
replica count was 0, and spec.minReplicas > 0, the status message
indicated "the desired replica count was less than the min replica
count". This was particularly confusing when `spec.MinReplicas = 1`. If
there was no `spec.minReplicas`, then the status message indicated "the
desired replica count was zero" which is more informative.
Update the calculation of status message so that if the desired replica
count is 0, we always display the clearer "the desired replica count was
zero" status message, even if spec.minReplicas > 0.

[fluentd-gcp addon] Trim too long log entries due to Stackdriver limitations
Stackdriver doesn't support log entries bigger than 100KB, so by default fluentd plugin just drops such entries. To avoid that and increase the visibility of this problem it's suggested to trim long lines instead.
