Also remove error messages that depended on ObjectKinds() - future
changes will potentially remove this interface and the replacements here
are equivalent.
Reduce all uses of Unstructured to the simpler form, and avoid asking
for mapper or typer unless it is required. Use Typed() for places that
previously used VersionedObject, and remove paths for versioned objects
from code that is now using unstructured.

Create kubectl's own instance of Scheme and Registry
Create kubectl's own instance of Registry and Scheme.
Switch most command that doesn't depend on internal types to use kubectl's own scheme and register.
There are some hack of registering the internal types in some of unit test now, they should be gone after switch to the external type.
Switch kubectl's factory code to use kubectl's scheme will create a lot of ripples.
I don't want make this PR a super giant PR, so I will do it in a followup PR.
Partially addressed #48564.
Copy the summary from https://github.com/kubernetes/kubernetes/pull/54533#issuecomment-340522302:
- creates pkg/kubectl/scheme (install.go and scheme.go) with
deps on properly vendored k8s.io packages.
- deletes about 80% percent of dependence on pkg/api/legacyscheme
- replaces direct dependence from pkg/kubectl on
pkg/apis/rbac
to a vendor style dependence on
k8s.io/api/rbac
and removes dependencies on rbac paths containing internalversion
- replaces almost 50% of direct dependence on pkg/api with (properly vendored)
k8s.io/api/core/v1
- deletes all of dependence on pkg/apis/policy and k8s.io/api/policy/v1beta1

This enables chunking in the resource builder to make it easy to
retrieve resources in pages and visit partial result sets. This adds
`--chunk-size` to `kubectl get` only so that users can get comfortable
with the use of chunking in beta. Future changes will enable chunking
for all CLI commands so that bulk actions can be performed more
efficiently.

pass labelSelector to server side opaquely

fix --local flag for kubectl commands
Fixes https://github.com/kubernetes/kubernetes/issues/47079
**Release note**:
```release-note
NONE
```
Fixes the `--local` flag for `kubectl set ...` sub-commands.
**As of the 1.7 release**, `PrinterForCommand` was updated to [use a mapper and typer for unstructured objects](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/util/factory_builder.go#L52), which further prevented the use of `--local` when there was no connection to an api server.
**before** (with no connection to a server)
```
$ kubectl set resources -f pod.json --limits=cpu=200m,memory=512Mi --local
error: unable to connect to a server to handle "pods": Get https://10.13.137.149:8443/api: dial tcp 10.13.137.149:8443: getsockopt: connection refused

make kubectl generic commands work with unstructured objects
part of making apply, edit, label, annotate, and patch work with third party resources
fixes#35149fixes#34413
prereq of:
https://github.com/kubernetes/kubernetes/issues/35496https://github.com/kubernetes/kubernetes/pull/40096
related to:
https://github.com/kubernetes/kubernetes/issues/39906https://github.com/kubernetes/kubernetes/issues/40119
kubectl is currently decoding any resource it doesn't have compiled-in to a ThirdPartyResourceData struct, which means it computes patches using that struct, and would try to send a ThirdPartyResourceData object to the API server when running `apply`
This PR removes the behavior that decodes unknown objects into ThirdPartyResourceData structs internally, and fixes up the following generic commands to work with unstructured objects
- [x] apply
- [x] decode into runtime.Unstructured objects
- [x] successfully use `--record` with unregistered objects
- [x] patch
- [x] decode into runtime.Unstructured objects
- [x] successfully use `--record` with unregistered objects
- [x] describe
- [x] decode into runtime.Unstructured objects
- [x] implement generic describer
- [x] fix other generic kubectl commands to work with unstructured objects
- [x] label
- [x] annotate
follow-ups for pre-existing issues:
- [ ] `explain` doesn't work with unregistered resources
- [ ] remove special casing of federation group in clientset lookups, etc
- [ ] `patch`
- [ ] doesn't honor output formats when persisting to server (`kubectl patch -f svc.json --type merge -p '{}' -o json` doesn't output json)
- [ ] --local throws exception (`kubectl patch -f svc.json --type merge -p '{}' --local`)
- [ ] `apply`
- [ ] fall back to generic JSON patch computation if no go struct is registered for the target GVK (e.g. https://github.com/kubernetes/kubernetes/pull/40096)
- [ ] ensure subkey deletion works in CreateThreeWayJSONMergePatch
- [ ] ensure type stomping works in CreateThreeWayJSONMergePatch
- [ ] lots of tests for generic json patch computation
- [ ] prevent generic apply patch computation among different versions
- [ ] reconcile treatment of nulls with https://github.com/kubernetes/kubernetes/pull/35496
- [ ] `edit`
- [ ] decode into runtime.Unstructured objects
- [ ] fall back to generic JSON patch computation if no go struct is registered for the target GVK
This patch adds the ability to specify an output format other than
"name" to `kubectl create ...`. It can be used in conjunction with the
`--dry-run` option. Converts unstructured objects into known types in
order to support all `--output` values.

Removes shorthand flag -w from kubectl apply
Fixes#37342.
A shorthand flag `-w` was introduced as flag `--prune-whitelist` for kubectl apply two weeks ago. Turned out it is not what we should do. Removing this shorthand flag before 1.5 release to prevent further issues.

Fix strategic patch for list of primitive type with merge sementic
Fix strategic patch for list of primitive type when the patch strategy is `merge`.
Before: we cannot replace or delete an item in a list of primitive, e.g. string, when the patch strategy is `merge`. It will always append new items to the list.
This patch will generate a map to update the list of primitive type.
The server with this patch will accept either a new patch or an old patch.
The client will found out the APIserver version before generate the patch.

Update kubectl create message when using --dry-run
`kubectl create <resource> <name> --dry-run` provides a misleading success
message.
When commands such as `kubectl new-app node` are run with a
`--dry-run` flag, they make this clear by appending a "(DRY RUN)"
string to the final output. `kubectl create <resource> <name> --dry-run`
does not do this, providing a potentially misleading output.
This patch appends a "(DRY RUN)" string to the end of a successful
message of `kubectl create` subcommands that support the `--dry-run` flag.
`kubectl create quota quota --dry-run`
```
resourcequota "quota" created
```
`kubectl create quota quota --dry-run`
```
resourcequota "quota" created (DRY RUN)
```
