Print a message if metrics are not yet available.
**What this PR does / why we need it**:
It takes about 80s to gather first metrics for the newly created pod. We would like to indicate this to the user, so that they don't mistake it for the command failure.
In case no metrics are found, we check whether there should be any, and if yes, print the appropriate message to the user.

Adding clusters to the list of valid resources printed by kubectl help
Ref https://github.com/kubernetes/kubernetes/issues/25592
Adding clusters to the list of valid resources printed by kubectl help with a clear message that it only works when talking to federation apiserver.
In future, we should replace the hard coded list with a dynamic list generated using APIServer's discovery API.
```release-note
Adding clusters to the list of valid resources printed by kubectl help
```

This changes clientcmd to skip the default cluster, but preserves the
behavior in kubectl. This prevents the possibility of an administrator
misconfiguration in kubelet or other server component from allowing a
third party who can bind to 8080 on that host from potentially
impersonating an API server and gaining root access.

Most of the contents of docs/ has moved to kubernetes.github.io.
Development of the docs and accompanying files has continued there, making
the copies in this repo stale. I've removed everything but the .md files
which remain to redirect old links. The .yaml config files in the docs
were used by some tests, these have been moved to test/fixtures/doc-yaml,
and can remain there to be used by tests or other purposes.

-->
**What this PR does / why we need it**:
The RC scaler uses Watch to monitor if the RC is scaled. The Watch was sent with resourceVersion=0, so the watch event it gets back starts from any point in the history, so the result is not valid.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
Probably will fix#30990Fix#30469
**Special notes for your reviewer**:
This breaks the load test because the reaper doesn't actually wait until all the pods are gone before it deletes the RC.
I haven't run the node-100 test myself to verify it fixes the problem though.

Optimise the ValidateBytes function
The PR optimise the "ValidateBytes" function in factory.go. Too much "if" branches is poor readability, use "switch" to look better.
1. When overlapping deployments are discovered, annotate them
2. Expose those overlapping annotations as warnings in kubectl describe
3. Only respect the earliest updated one (skip syncing all other overlapping deployments)
4. Use indexer instead of store for deployment lister

Basic scaler/reaper for petset
Currently scaling or upgrading a petset is more complicated than it should be. Would be nice if this made code freeze on friday. I'm planning on a follow up change with generation number and e2es post freeze.

remove duplicate errors from aggregate error outputs
release-label-none
Duplicate error messages are sometimes shown when displaying aggregate errors:
`$ kubectl label pod/database-1-fn0r7 qwer1345%$$#=self`
```
* metadata.labels: Invalid value: "qwer1345%5602#": name part must match the regex ([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9] (e.g. 'MyName' or 'my.name' or '123-abc')
* metadata.labels: Invalid value: "qwer1345%5602#": name part must match the regex ([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9] (e.g. 'MyName' or 'my.name' or '123-abc')
