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.

Make sure the StatusCode is taken into account in DoRaw()
**What this PR does / why we need it**:
Currently if there is an error (not found) the error printed out
is to do with the inablity to convert an empty body into the expected json.
This patch will fill in the err correctly.
example of before (with NotFound error):
$ kubectl top node
failed to unmarshall heapster response: json: cannot unmarshal object into Go value of type []v1alpha1.NodeMetrics
Now:
$ kubectl top node
the server could not find the requested resource (get services http:heapster:)

Avoid sorting lists when unnecessary
I've seen ThreadSafeMap::List consuming ~30% of whole CPU usage, spending the whole time in sorting (while it is in fact completely unneded).

Add ScaleExpansion to client v1.4
**What this PR does / why we need it**:
The generated v1.4 did not carry over the complete ScaleExpansion interface. The unversioned client is using this interface and should be in sync with generated client.

```release-note
NONE

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

Followup to #30839.
I'm not convinced this is a super great idea but I'll throw it out and let others decide.

Remove implicit Prometheus metrics from client
**What this PR does / why we need it**: This PR starts to cut away at dependencies that the client has.

```release-note
The implicit registration of Prometheus metrics for request count and latency have been removed, and a plug-able interface was added. If you were using our client libraries in your own binaries and want these metrics, add the following to your imports in the main package: "k8s.io/pkg/client/metrics/prometheus".

Add support for the standard objectmeta field selectors
certificates API was missing standard field selectors (noticed in 4120179db5 (r75413160))
also silences client-side warnings when using field selectors that don't have a registered client-side transformation (no functional change, since we were already returning the original field/value). if we want to trend toward embedding less conversion logic in our clients, I don't see us fully duplicating field selector conversions client-side to make that warning disappear.

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.

Attempt to ensure entire resp body is read
**What this PR does / why we need it**: Enables the re-use of TCP connections when code fails to read the entire body of the response.
**Which issue this PR fixes**: fixes#30975
**Special notes for your reviewer**:
This is a best effort approach. It only attempts to drain the body of the response if it's less than 1k. It seems like a reasonable barrier at which to give up and just use a new TCP connection.

Add a short `-n` for `kubectl --namespace`
fixes#24078
`--namespace` is a very common flag for nearly every `kubectl` command we have. We should claim `-n` for it.
Convert single GV and lists of GVs into an interface that can handle
more complex scenarios (everything internal, nothing supported). Pass
the interface down into conversion.
