```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.

[GarbageCollector] measure latency
First commit is #27600.
In e2e tests, I measure the average time an item spend in the eventQueue(~1.5 ms), dirtyQueue(~13ms), and orphanQueue(~37ms). There is no stress test in e2e yet, so the number may not be useful.

Run goimport for the whole repo
While removing GOMAXPROC and running goimports, I noticed quite a lot of other files also needed a goimport format. Didn't commit `*.generated.go`, `*.deepcopy.go` or files in `vendor`
This is more for testing if it builds.
The only strange thing here is the gopkg.in/gcfg.v1 => github.com/scalingdata/gcfg replace.
