Node Conformance Test: Add system verification

New command: "kubeadm token generate"
As part of #33930, this PR adds a new top-level command to kubeadm to just generate a token for use with the init/join commands. Otherwise, users are left to either figure out how to generate a token on their own, or let `kubeadm init` generate a token, capture and parse the output, and then use that token for `kubeadm join`.
At this point, I was hoping for feedback on the CLI experience, and then I can add tests. I spoke with @mikedanese and he didn't like the original propose of `kubeadm util generate-token`, so here are the runners up:
```
$ kubeadm generate-token # <--- current implementation
$ kubeadm generate token # in case kubeadm might generate other things in the future?
$ kubeadm init --generate-token # possibly as a subcommand of an existing one
```
Currently, the output is simply the token on one line without any padding/formatting:
```
$ kubeadm generate-token

Add --force to kubectl delete and explain force deletion
--force is required for --grace-period=0. --now is == --grace-period=1.
Improve command help to explain what graceful deletion is and warn about
force deletion.
Part of #34160 & #29033
```release-note
In order to bypass graceful deletion of pods (to immediately remove the pod from the API) the user must now provide the `--force` flag in addition to `--grace-period=0`. This prevents users from accidentally force deleting pods without being aware of the consequences of force deletion. Force deleting pods for resources like StatefulSets can result in multiple pods with the same name having running processes in the cluster, which may lead to data corruption or data inconsistency when using shared storage or common API endpoints.

kubectl: make edit work with lists again
@kubernetes/kubectl this is fixing https://github.com/kubernetes/kubernetes/issues/20519 and slightly changes the behavior of --recursive when the directory that is being edited has files with errors. Previously since `edit` was working on an object basis, bad objects would be skipped and the editor would load the next object. We want to load multiple objects in the same list and it's impossible to load invalid objects in a list so --recursive will not work if there is any error in the directory. I think this is an acceptable trade-off.

Switch DisruptionBudget api from bool to int allowed disruptions [only v1beta1]
Continuation of #34546. Apparently it there is some bug that prevents us from having 2 different incompatibile version of API in integration tests. So in this PR v1alpha1 is removed until testing infrastructure is fixed.
Base PR comment:
Currently there is a single bool in disruption budget api that denotes whether 1 pod can be deleted or not. Every time a pod is deleted the apiserver filps the bool to false and the disruptionbudget controller sets it to true if more deletions are allowed. This works but it is far from optimal when the user wants to delete multiple pods (for example, by decreasing replicaset size from 10000 to 8000).
This PR adds a new api version v1beta1 and changes bool to int which contains a number of pods that can be deleted at once.

Build: Use checksum to rsync results
If dependencies are touched, the Makefile will detect that tools like
deepcopy-gen need to be rebuilt. It will rebuild them, but if Go decides the
dependencies are not ACTUALLY updated (maybe it was a test file - known
limitation of the current Makefile), it does not touch the resulting binary.
The Makefile touches the result explicitly to mark that the dep change has
been handled. But rsync blows away that change with the older file, and
helpfully preserves the timestamp. This repeats on every build.
Now rsync ignores it if the checksum is the same. Result = faster build.

build: Fix version generation.
This PR provides update to version string generation procedure to handle additional case - working on branch delivered from release tag, instead of working on `-(alpha|beta).no` suffixed tag.
Reason of it is that actually if someone would start working on branch forked from release tag (`v1.4.1` for example), will add some commits and then would try to build k8s/run conformance tests - will end up with broken version string in form similar to `v1.4.1.X+YYYY` where `X` is a dictance/number of commits from base tag and `YYYY` will be first 14 characters from commit hash.
Such version - containing four dotted parts is rejected during conformance tests with error similar to:
```
/go/src/k8s.io/kubernetes/_output/dockerized/go/src/k8s.io/kubernetes/test/e2e/kubectl.go:843

/go/src/k8s.io/kubernetes/_output/dockerized/go/src/k8s.io/kubernetes/test/e2e/framework/util.go:413
```
This PR provides a cure for this situation creating version string in form `v1.4.1-X+YYYY` which then should be readable for version validation checks.

```release-note

add optional mutation checks for shared informer cache
We need to make sure that no one is mutating caches if they're using a shared informer. It is important that whatever is tracking those changes gets the object *before* anyone else possibly could.
This adds the ability to track the original objects in the cache and their current values. Go doesn't have an exit hook or a way to say "wait for non-daemon go-funcs to complete before exit", so this runs a gofunc on a loop that can panic the entire process. It's gated behind an env var.

1. Fixing how we handle terminal width in help. Some sections like the flags use the entire available width, while others like long descriptions breaks lines but don't follow a well established max width (screenshot below). This PR adds a new responsive writer that will adjust to terminal width and set 80, 100, or 120 columns as the max width, but not more than that given POSIX best practices and recommendations for better readability.
2. Adds our own normalizers for long descriptions and cmd examples which allows us better control about how things like lists, paragraphs, line breaks, etc are printed. Features markdown support. Looks like `templates.LongDesc` and `templates.Examples` instead of `dedent.Dedend`.
3. Allows simple reordering and reuse of help and usage sections.
3. Adds `verify-cli-conventions.sh` which intends to run tests to make sure cmd developers are using what we propose as [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md). Just a couple simple tests for now but the framework is there and it's easy to extend.
4. Update [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md) to use our own normalizers instead of `dedent.Dedent`.

local-up: Add option to guess binary path
This adds a `-O` flag which guesses the right output directory.
The reason for having two flags, not one, is because bash's `getopt` doesn't let you do optional arguments easily, so having both makes the code simpler.
I also removed the redundant empty check; the bash argument check meant that was never hit.

add ownerref permission checks
Adds an admission plugin that ensures that anyone adding an `ownerReference` to a resource has delete rights on the resource they're setting up a delete for.
@caesarxuchao example admission plugin that tests for ownerReference diffs and uses an authorizer to drive the decision.

Add flags for alternative API and discovery ports
**What this PR does / why we need it**:
We had many issues reported due to the fact that we are using port 443 by default, and we should allow users to override whatever defaults we pick. This doesn't touch on `localhost:8080` yet, which should just generally get rid of.
**Which issue this PR fixes**: fixes#34311#34307#33638
**Special notes for your reviewer**: cc @pires
**Release note**:
```release-note
Add `kubeadm` flags `--api-port` and `--discovery-port`, change default API port to 6443

clientgen: allow to pass custom apiPath when generating client sets
This PR allow to pass the `--clientset-api-path` parameter to clientgen that allows to customize the default API path set in clients. This allows projects like OpenShift to re-use the client with different API path (`/oapi` in our case).
