Implement kubeadm bootstrap token management
Creates bootstrap tokens as secrets per the specification in #30707
_WARNING_: These are not currently hooked up to the discovery service or the token it creates.
Still TODO:
- [x] delete tokens
- [x] merge with #35144 and adopt it's testing approach
- [x] determine if we want wholesale json output & templating like kubectl (we do not have an API object with the data we want here) may require a bit of plumbing.
- [x] allow specifying a token duration on the CLI
- [x] allow configuring the default token duration
- [x] hook up the initial token created during init
Sample output:
```
(root@centos1 ~) $ kubeadm token create
Running pre-flight checks
<cmd/token> Token secret created: f6dc69.c43e491752c4a0fd
(root@centos1 ~) $ kubeadm token create
Running pre-flight checks
<cmd/token> Token secret created: 8fad2f.e7b78c8a5f7c7b9a

Add test for CronJob generator
Per @janetkuo request this was split from #38614, it adds test for `CronJob` generator, and additionally copy labels to `JobTemplate`, to be consistent with how `Job` generator works.
Adds kubeadm subcommands to create, list, and delete bootstrap tokens.
Tokens can be created with a TTL duration, or 0 for tokens that will not
expire. The create command can also be used to specify your own token
(for use when bootstrapping masters and nodes in parallel), or update an
existing token's secret or ttl.
Marked "ex" for experimental for now as the boostrap controllers are not
yet hooked up in core.

Reduce decode times by changing the kubectl.Filter(runtime.Object, *PrintOptions)'s return values
**What this PR does / why we need it**:
In kubectl/cmd/get.go, we use the function filterFuncs.Filter() to decode data and filter the object. But in the following function printer.PrintObj() decodes the data again.
I made these modifications to reduce the decoding times by changing the filterFuncs.Filter()'s returned values. We can get the decoded object from this function and pass it to the following printer.PrintObj(), so not to waste time to decode again.

prevent negotation on connections that dont' require it
Not all clientconfigs require negotiation. Before there was a patch (hardcoded to an instance variable) that allowed this. This updates the code to allow the same as before.

Rename "release_1_5" clientset to just "clientset"
We used to keep multiple releases in the main repo. Now that [client-go](https://github.com/kubernetes/client-go) does the versioning, there is no need to keep releases in the main repo. This PR renames the "release_1_5" clientset to just "clientset", clientset development will be done in this directory.

Prevent "patched" output on obj not patched
**Release note**:
```release-note
release-note-none
```
This patch compares an original object against a patched object returned
from the server and only announces that the object was successfully
patched if the object returned from the server does not equal the
original object.

Remove json serialization annotations from internal types
fixes#3933
Internal types should never be serialized, and including json serialization tags on them makes it possible to accidentally do that without realizing it.
fixes in this PR:
* types
* [x] remove json tags from internal types
* [x] fix references from serialized types to internal ObjectMeta
* generation
* [x] remove generated json codecs for internal types (they should never be used)
* kubectl
* [x] fix `apply` to operate on versioned object
* [x] fix sorting by field to operate on versioned object
* [x] fix `--record` to build annotation patch using versioned object
* hpa
* [x] fix unmarshaling to internal CustomMetricTargetList in validation
* thirdpartyresources
* [x] fix encoding API responses using internal ObjectMeta
* tests
* [x] fix tests to use versioned objects when checking encoded content
* [x] fix tests passing internal objects to generic printers
follow ups (will open tracking issues or additional PRs):
- [ ] remove json tags from internal kubeconfig types (`kubectl config set` pathfinding needs to work against external type)
- [ ] HPA should version CustomMetricTargetList serialization in annotations
- [ ] revisit how TPR resthandlers encoding objects
- [ ] audit and add tests for printer use (human-readable printer requires internal versions, generic printers require external versions)
- [ ] add static analysis tests preventing new internal types from adding tags
- [ ] add static analysis tests requiring json tags on external types (and enforcing lower-case first letter)
- [ ] add more tests for `kubectl get` exercising known and unknown types with all output options

Remove "pod xxx deleted" message from kubectl run --rm
This is a follow-on to https://github.com/kubernetes/kubernetes/issues/28695
Its unnecessary to print the message when the user asked for it.
We should only show a msg (error) when we didn't do what they asked.
Also showing this in a "kubectl run" is bad because it then
gets appended to the user's output and they would then have to strip
it off if they want to use the output in some follow-on processing.
