Calculate patches for commands using input version
Fixes#53040
the encoder used for encoding these objects while calculating patches does not have sufficient information to select a correct version when the object does not exist in all versions of a target group (like replicasets not existing in apps/v1beta1)
this PR wraps the encoder to first convert to the same version used to read the object (based on the mapping's GroupVersion)
long-term, we should switch UpdatePodSpecForObject to work on versioned objects and v1.PodSpec and avoid conversion altogether
```release-note
Fixes an issue with `kubectl set` commands encountering conversion errors for ReplicaSet and DaemonSet objects

Fix return 0 error in DefaultSubCommandRun
Fixes https://github.com/kubernetes/kubernetes/issues/50644
@mengqiy most of our command didn't return 1 when error, is because it invoke `DefaultSubCommandRun` which created in this pr https://github.com/kubernetes/kubernetes/pull/35206, I'm not sure if it's ok to directly add an `os.Exit` in that function, so also cc @juanvallejo @fabianofranz for review.
also @apelisse @mengqiy I think we don't have any test for check return value now ? cmiiw, I will add some test in test-cmd since it's easy to write scripts check return value, wdyt ?

Allow kubectl cp large amounts of files from container
When we try to copy out a dir with large amounts of files from container, we hit such error:

kubectl cp mypod:/ ./a/
tar: Removing leading `/' from member names
tar: Removing leading `/' from hard link targets
error: open a/usr/share/zoneinfo/Asia/Rangoon: too many open files

This is because kubectl opens too many files at the same. We should close them after Write() function.

Rather than printing `Scaling the resource failed with: An Error; Current resource version Unknown` whenever a ScalerError occurs and a resource version is not known, we should avoid printing the resource version part of the error message in order to avoid potential confusion by a user.

kubectl: Fix golint warnings for plugins/*
**What this PR does / why we need it**:
We currently have an entry in `hack/.golint_failures` for `pkg/kubectl/plugins`. If we lint the files in `plugins/` then we can safely remove this entry.
`golint` emits the following warnings (only one of each type shown)
```
exported method EnvList.Slice should have comment or be unexported
error var IncompletePluginError should have name of the form ErrFoo
func name will be used as plugins.PluginsEnvVarPluginLoader by other packages, and that stutters; consider calling this EnvVarPluginLoader
```
This PR clears all `golint` warnings from `kubectl/plugins/`.
1. Remove entry from `hack/.golint_failures`
2. Add missing documentation to exported types and functions.
3. Rename error variables to `ErrFoo`.
4. Rename `PluginsEnvVarPluginLoader` to `KubectlPluginsPathPluginLoader` (mirrors env var name).
5. Rename `XDGDataPluginLoader` to `XDGDataDirsPluginLoader` (to make uniform change above).
**Special notes for your reviewer**:
Felt a bit dirty doing this cleanup because the code in `plugins/` is particularly clean and well written already.

```release-note

ensure unstructured resources in kubectl get
Related downstream issue: https://github.com/openshift/origin/issues/16064
Ensure we are dealing with unstructured objects before attempting to
compose into an unstructured list.
`$ kubectl get ...` [assumes all resources returned from a resource builder are unstructured objects](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/get.go#L355). This leads to a panic when dealing with non-unstructured objects.
This patch ensures we are dealing with unstructured objects before attempting to
compose into an unstructured list.
