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:
```bash
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.

NONE

ignore unknown resource version in scaler error
**Release note**:
```release-note
NONE
```
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**:
```release-note
NONE
```

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.

Adds documentation to the help for generic secret creation that
specifies how to create a secret using values from both a literal
and a file. Also cleans up some of the formatting.
Move negative check for testing "not patched" output to test-cmd-util.sh
as exiting with code 1 was causing patch_test.go to fail when the error
was expected as part of the test.

Simplify describe events table
The describe table for events is not easy to read and violates other
output guidelines. Change to use spaces (we don't use tabs in formal
output for tables). Remove columns that are not normally needed or
available on events.
Example for pods:
```
...
QoS Class: BestEffort
Node-Selectors: role=app
Tolerations: <none>
Events:
Type Reason Age From Message
---- ------ ---- ---- -------
Normal Pulling 1h (x51 over 5h) kubelet, origin-ci-ig-n-gj0x pulling image "registry.svc.ci.openshift.org/experiment/commenter:latest"
Normal BackOff 8m (x1274 over 5h) kubelet, origin-ci-ig-n-gj0x Back-off pulling image "registry.svc.ci.openshift.org/experiment/commenter:latest"
Warning FailedSync 3m (x1359 over 5h) kubelet, origin-ci-ig-n-gj0x Error syncing pod
```
Puts the type first (separate important from not), then reason (which is
the most impactful scanning field). Collapses first seen, last seen, and
times into a single field, since most of the time you care about the
last time the event happened, not the first time.
@kubernetes/sig-cli-pr-reviews sorry for the last minute drop, but the usability of this is driving me up the wall and I can't take it anymore. Would like to slip this into 1.8 so that I can debug things without dying a little inside.
Fixes#47715
```release-note
The event table output under `kubectl describe` has been simplified to show only the most essential info.
```
