In an effort to expand the existing pool of reviewers and establish a
two-tiered review process (first someone lgtms and then someone
experienced in the project approves), we are adding new reviewers to
existing owners files.
If You Care About the Process:
------------------------------
We did this by algorithmically figuring out who’s contributed code to
the project and in what directories. Unfortunately, that doesn’t work
well: people that have made mechanical code changes (e.g change the
copyright header across all directories) end up as reviewers in lots of
places.
Instead of using pure commit data, we generated an excessively large
list of reviewers and pruned based on all time commit data, recent
commit data and review data (number of PRs commented on).
At this point we have a decent list of reviewers, but it needs one last
pass for fine tuning.
Also, see https://github.com/kubernetes/contrib/issues/1389.
TLDR:
-----
As an owner of a sig/directory and a leader of the project, here’s what
we need from you:
1. Use PR https://github.com/kubernetes/kubernetes/pull/35715 as an example.
2. The pull-request is made editable, please edit the `OWNERS` file to
remove the names of people that shouldn't be reviewing code in the
future in the **reviewers** section. You probably do NOT need to modify
the **approvers** section. Names asre sorted by relevance, using some
secret statistics.
3. Notify me if you want some OWNERS file to be removed. Being an
approver or reviewer of a parent directory makes you a reviewer/approver
of the subdirectories too, so not all OWNERS files may be necessary.
4. Please use ALIAS if you want to use the same list of people over and
over again (don't hesitate to ask me for help, or use the pull-request
above as an example)

pkg/apiserver: split up monolithic package
**Based on** https://github.com/kubernetes/kubernetes/pull/38191
This is a first step to integrate pkg/apiserver with pkg/genericapiserver into a common package structure. For this
- pkg/apiserver is cleaned up from code which does not belong there,
- split up into pkg/apiserver, pkg/apiserver/handlers{,/negotation,/helpers,/errors}

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.
- move rest handler into handlers package
- move errors into handlers/errors package
- move negotation code into handlers/negotation package
- move http response writer helpers into handlers/responsewriter package
- split up pkg/apiserver/apiserver.go
Note: this is only an intermediate step towards a proper genericapiserver
package hierarchy.

Prevent json decoder panic on invalid input
Related downstream issue: https://github.com/openshift/origin/issues/12132
```
# Can be replicated on kubectl with:
$ cat panic.json
{
"kind": "Pod",
"apiVersion": "v1",
"metadata": {
"name": "",
"labels": {
"name": ""
},
"generateName": "",
"namespace": "",
"annotations": []
},
"spec": {}
},
$ kubectl create -f panic.json --validate=false
```
**Release note**:
```release-note
release-note-none
```
This patch handles cases where `ioutil.ReadAll` will return a single
character output on an invalid json input, causing the `Decode` method
to panic when it tries to calculate the line number for the syntax
error. The example below would cause a panic due to the trailing comma
at the end:
```
{
"kind": "Pod",
"apiVersion": "v1",
"metadata": {
"name": "",
"labels": {
"name": ""
},
"generateName": "",

Refactor port allocation logic a little, deflake tests.
This should fix#38323 for real.
@xiangpengzhao @rmmh @justinsb
Switch to manually cranking over the port filling logic, since there was a race between the allocate logic and the check to see if the port was freed up.

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.

Reduce amount of allocations in cacher
Currently we are unnecessary copying stuff around in cacher.
This results in __tens of megabytes__ of allocations per __second__ in large clusters. This in turn results in expensive GC. Should help with metrics.

Remove two zany unit tests.
These two tests aren't unit tests in the usual sense. We can consider switching them to run as verify checks, but I'm not convinced that they're even necessary.
They essentially work by searching their code for public functions with signatures that look like `FitPredicate`, then they shell out to grep to see that they're used somewhere in the source tree. This will never work in bazel.

rename constant MaxPatchConflicts to maxRetryWhenPatchConflicts
**What this PR does / why we need it**:
1. literally `MaxPatchConflicts` means max number of patch conflicts allowed during a patch operation. but actually in codes it is used to indicate max number of patch retry when patch conflicts happened.
2. there is no need to export this constant because it is only used in `resthandler.go` and shouldn't be used in other packages.

Remove dead code in `pkg/registry/generic/registry/store.go`
Fixes#38822
Depending on the intent of the original code, the correct fix may instead be:
```go
if name, ok := p.MatchesSingle(); ok {
key, err := e.KeyFunc(ctx, name)
if err != nil {
return nil, err
}
w, err := e.Storage.Watch(ctx, key, resourceVersion, p)
if err != nil {
return nil, err
}
if e.Decorator != nil {
return newDecoratedWatcher(w, e.Decorator), nil
}
return w, nil
// if we cannot extract a key based on the current context, the optimization is skipped
}

genericapiserver: turn APIContainer.SecretRoutes into a real ServeMux
The secret routes `Mux` is actually a `http.ServeMux` and we are type-casting to it. For downstream we want to wrap it into a restful container which also needs a real `http.ServeMux`.
