Automatic merge from submit-queue (batch tested with PRs 59353, 59905, 53833).

Graduate kubeletconfig API group to beta Regarding https://github.com/kubernetes/features/issues/281, this PR moves the kubeletconfig API group to beta. After #53088, the KubeletConfiguration type should not contain any deprecated or experimental fields, and we should not have to remove any more fields from the type before graduating it to beta. We need the community to double check for two things, however: 1. Are there any fields currently in the KubeletConfiguration type that you were going to mark deprecated this quarter, but haven't yet? 2. Are there any fields currently in the KubeletConfiguration type that are experimental or alpha, but were not explicitly denoted as such? Please comment on this PR if you can answer "yes" to either of those two questions. Please cc anyone with a stake in the kubeletconfig API, so we get as much coverage as possible. /cc @thockin @dchen1107 @Random-Liu @yujuhong @dashpole @tallclair @vishh @abw @freehan @dnardo @bowei @MrHohn @luxas @liggitt @ncdc @derekwaynecarr @mikedanese @kubernetes/sig-network-pr-reviews, @kubernetes/sig-node-pr-reviews ```release-note action required: The `kubeletconfig` API group has graduated from alpha to beta, and the name has changed to `kubelet.config.k8s.io`. Please use `kubelet.config.k8s.io/v1beta1`, as `kubeletconfig/v1alpha1` is no longer available. ``` **TODO:** - [x] Move experimental/non-gated-alpha/soon-to-be-deprecated fields to `KubeletFlags` - [x] #53088 - [x] #54154 - [x] #54160 - [x] #55562 - [x] #55983 - [x] #57851 - [x] Lift embedded structure out of strings - [x] #53025 - [x] #54643 - [x] #54823 - [x] #55254 - [x] Resolve relative paths against the location config files are loaded from - [x] #55648 - [x] Rename to `kubelet.config.k8s.io` - [x] Comments - [x] Make sure existing comments at least read sensibly. - [x] Note default values in comments on the versioned struct. - [x] Remove any reference to default values in comments on the internal struct. - [x] Most fields should be `+optional` and `omitempty`. Add where necessary. ~Where omitted, explicitly comment.~ Edit: We should not distinguish between nil and empty, see below items. - [x] Ensure defaults are specified via `pkg/kubelet/apis/kubelet.config.k8s.io/v1beta1/defaults.go`, not `cmd/kubelet/app/options/options.go`. - [x] #57770 - [x] Ensure kubeadm does not persist v1alpha1 KubeletConfiguration objects (or feature-gates this functionality) - [x] Don't make a distinction between empty and nil, because of #43203. - [x] #59515 - [x] #59681 - [x] Take the opportunity to fix insecure Kubelet defaults @tallclair - [x] #59666 - [x] Remove CAdvisorPort from KubeletConfiguration wrt #56523. - [x] #59580 - [x] Hide `ConfigTrialDuration` until we're more sure what to do with it. - [x] #59628 - [x] Fix `// default: x` comments after rebasing on recent changes. |

Kubernetes
Kubernetes is an open source system for managing containerized applications across multiple hosts; providing basic mechanisms for deployment, maintenance, and scaling of applications.
Kubernetes builds upon a decade and a half of experience at Google running production workloads at scale using a system called Borg, combined with best-of-breed ideas and practices from the community.
Kubernetes is hosted by the Cloud Native Computing Foundation (CNCF). If you are a company that wants to help shape the evolution of technologies that are container-packaged, dynamically-scheduled and microservices-oriented, consider joining the CNCF. For details about who's involved and how Kubernetes plays a role, read the CNCF announcement.
To start using Kubernetes
See our documentation on kubernetes.io.
Try our interactive tutorial.
Take a free course on Scalable Microservices with Kubernetes.
To start developing Kubernetes
The community repository hosts all information about building Kubernetes from source, how to contribute code and documentation, who to contact about what, etc.
If you want to build Kubernetes right away there are two options:
You have a working Go environment.
$ go get -d k8s.io/kubernetes
$ cd $GOPATH/src/k8s.io/kubernetes
$ make
You have a working Docker environment.
$ git clone https://github.com/kubernetes/kubernetes
$ cd kubernetes
$ make quick-release
For the full story, head over to the developer's documentation.
Support
If you need support, start with the troubleshooting guide, and work your way through the process that we've outlined.
That said, if you have questions, reach out to us one way or another.
