`kubectl alpha diff` lets you diff your resources against live
resources, or last applied, or even preview what changes are going to be
applied on the cluster.
This is still quite premature, and mostly untested.
In RunClusterInfo, We try to connect to the api service and get some
information, but we just ignore the errors from Do().Visit(). We should
return the error returned by Do().Visit() so the "kubectl cluster-info"
would fail correctly with an error code.

kubectl resource builder to use versioned list
Switch to using a versioned listed when return an object from the resource builder.
This is necessary to allow cli's built outside the kubernetes/kubernetes repo to vendor the resource builder logic without vendoring all of Kubernetes.
The following commands call the modified function. (identified by changing the function name and recompiling)
- [x] `attach`
- pkg/kubectl/cmd/attach.go:155: builder.Do().Object
- passes to `AttachablePodForObject` which does not support Lists of any kind
- [x] `get`
- pkg/kubectl/cmd/get.go:251: r.Object
- [x] check if isList with `IsListType` -> `GetItemsPtr` -> check for presence of `Items` field
- [x] pass to `ResourceVersion` -> `CommonAccessor` -> checks for `metav1.ListInterface` (which this PR introduces a compile time check to ensure v1.List implements this)
- [x] pass to `ExtractList` -> checks if items implement `runtime.RawExtension`
- [x] `rolling_update`
- pkg/kubectl/cmd/rollingupdate.go:207: request.Object
- only accepts lists of length 1. updated in PR to support both api.List and v1.List
- [x] `rollout_status`
- pkg/kubectl/cmd/rollout/rollout_status.go:107: r.Object
- passes to `ResourceVersion` -> `CommonAccessor` -> checks for `metav1.ListInterface`

Previously, the fake RESTClient in client-go required a Registry. It
used the Registry to fetch the GroupVersion for the fake client.
However, the way it did so was dubious in some cases (it hard-coded the
default API group in places), and not strictly necssary.
This updates the fake client to just recieve the GroupVersion and
internal group name directly, instead of requiring a Registry, so that
it can be consumed in unit tests where a Registry isn't necessarily
readily available (e.g. elsewhere in client-go).

pkg/api: extract Scheme/Registry/Codecs into pkg/api/legacyscheme
This serves as
- a preparation for the pkg/api->pkg/apis/core move
- and makes the dependency to the scheme explicit when vizualizing
left depenncies.
The later helps with our our efforts to split up the monolithic repo
into self-contained sub-repos, e.g. for kubectl, controller-manager
and kube-apiserver in the future.

Provide aggregated validation errors for version and kind
Currently the validation checks is done individually for version and
kind group. For example, if user provided yaml file is missing apiVersion
and kind fields, first they will receive error on apiVersion. Once user
update the file and try to recreate, an error on missing kind is displayed.
The behavior is same for wrong types of the fields.
These errors should be aggregated and displayed.
Examples of current validation:
1
test.yaml is missing apiVersion and kind:
$kubectl.sh create -f /home/sahdev/go/src/bugfixes/test.yaml
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: apiVersion not set; if you choose to ignore these errors, turn validation off with --validate=false
2.
test.yaml is fixed for apiVersion but missing kind:
$kubectl.sh create -f /home/sahdev/go/src/bugfixes/test.yaml
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: kind not set; if you choose to ignore these errors, turn validation off with --validate=false
Examples with aggregated validation:
1.
error: error validating "/home/sahdev/go/src/bugfixes/test.yaml": error validating data: [apiVersion not set, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false
2.
error: error validating "/home/sahdev/go/src/bugfixes/testmix.yaml": error validating data: [apiVersion isn't string type, kind not set]; if you choose to ignore these errors, turn validation off with --validate=false

Update rules_go, repo-infra, and rules_docker dependencies
**What this PR does / why we need it**: several of our bazel dependencies were getting pretty old, since they required bazel 0.5.4+ but there were various failures if we tried to use them with bazel 0.5.4.
Now that bazel 0.6.0 (and 0.6.1) have been out for a while, we can bump our dependencies and get a number of fixes and new functionality.
x-ref #52677 and others
**Special notes for your reviewer**:
* This will now explicitly require bazel 0.6.0+ to build kubernetes.
* Our staging directories are causing some issues for `gazelle`; it wants to set `importpath = "k8s.io/kubernetes/staging/src/k8s.io/blah"` instead of `importpath = "k8s.io/blah"`. I'm not sure what is the correct way to fix this; what we're doing here is pretty weird and nonstandard. I've used a `sed` substitution for now.
* The `-proto=default` option of `gazelle` has a number of bugs right now (https://github.com/bazelbuild/rules_go/issues/888, https://github.com/bazelbuild/rules_go/issues/900, https://github.com/bazelbuild/rules_go/issues/907), so I am forcing the legacy behavior.

improve kubectl cp command in several ways
**Release note**:
"kubectl cp" process soft link in better ways as well as some little bugs
**Soft link**:
before this patch
"kubectl cp" command will copy the soft link to destination as an empty regular file
after this patch
"kubectl cp" command will behave the same as tar command
this patch improves it on both from container and to container
**some bugs**
1.from container to host
a.when copy a file ends with '/', it will cause a panic.
for example, container gakki has a regular file /tmp/test, then run command
_kubectl cp gakki:/tmp/test/ /tmp_
a panic happens
b.when copy a file which does not exist in container, the command ends up without
any error information
2.from host to container
a.when run command like
kubectl cp "" gakki:/tmp
it will try cp current directory to container, in other words, this command works
the same as kubectl cp . gakki:/tmp
b.current cp command will omit an empty directory
A.support soft link better

preserve specified destination path
**Release note**:
```release-note
"kubectl cp" updated to honor destination names
```
**Before**
```
$ kubectl cp foo_dir pod_name:/tmp/bar_dir
$ kubectl exec pod_name -it -- /bin/sh
sh-4.2$
sh-4.2$ ls /tmp
sh-4.2$ foo_dir
```
**After**
```
$ kubectl cp foo_dir pod_name:/tmp/bar_dir
$ kubectl exec pod_name -it -- /bin/sh
sh-4.2$
sh-4.2$ ls /tmp
sh-4.2$ bar_dir
```
**Notable changes to `kubectl cp` After This Patch**
- Copying a directory `bar_dir` to an existing directory in the pod will copy the directory itself, rather than just the file contents:
```bash
*Before*
> remote-pod-shell$ ls /tmp
existing_remote_dir
$ kubectl cp ./my/local/awesome_dir mypod:/tmp/existing_remote_dir
> remote-pod-shell$ ls /tmp
existing_remote_dir
awesome_dir
```
```bash
*After*
> remote-pod-shell$ ls /tmp
existing_remote_dir
$ kubectl cp ./my/local/awesome_dir mypod:/tmp/existing_remote_dir
> remote-pod-shell$ ls /tmp
existing_remote_dir
> remote-pod-shell$ ls /tmp/existing_remote_dir
awesome_dir
```
```
*Before*: Directory contents were merged if a local and remote directory shared the same name
*After*: A new name will be honored for the copied local directory on the remote pod.
If a new name was not specified for the local directory being copied, and it shares the
same name as an already-existing directory on the pod, current behavior will follow and
its contents will be added to those of the already-existing directory.
```
```
*Before*: If a trailing slash (e.g. kubectl cp ./local/dir pod:/tmp) was not added to a directory
name in the destination path (...:/tmp vs /tmp/...), when copying to a pod, `kubectl`
would attempt to copy the local directory under the parent of the remote directory
rather than inside of it.
*After*: Slashes do not alter the behavior of the command, or destination of the intended
source file or directory. With a command such as (kubectl cp ./local_dir pod:/tmp),
`local_dir` would be copied inside of <pod:/tmp> (an error is returned if pod:/tmp is
a file).

Remove duplicate code fixing empty name error
**What this PR does / why we need it**:
Removes two helper functions which have duplicate code; code can be safely added to the calling function. This does add an extra parameter to calls. Since the helpers are file local functions with only two call sites it is trivial to see that this PR maintains current logic.

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)

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:
```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.

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.
