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
```
**after** (with no connection to a server)
```
$ kubectl set resources -f pod.json --limits=cpu=200m,memory=512Mi --local
NAME READY STATUS RESTARTS AGE
mypod 0/1 0 <unknown>
```
cc @smarterclayton @fabianofranz
Get command now uses metadata x-kubernetes-print-columns, if present, in Openapi schema
to format output for a resource. This functionality is guarded by a boolean
flag 'use-openapi-print-columns'.
This fixes#38779.
This allows us to avoid case in which printers.GetStandardPrinter
returns nil for both printer and err removing any potential panics that
may arise throughout kubectl commands.
Please see #38779 and #38112 for complete context.
Add comment explaining adding handlers to printers.HumanReadablePrinter
also remove an unnecessary conversion of printers.HumanReadablePrinter
to printers.ResourcePrinter.

Refactor printers and describers into their own package.
This sets the stage for using printer code from the server side (decoupled from kubectl) and loosens the coupling between kubectl and the printers. `pkg/printers` contains interfaces and has an import restriction against pulling in API specific code, while `pkg/printers/internalversion` can be used for internal types.
Add a method on `Factory` for retrieving PrinterForCommand which uses the Scheme and RESTMapper from the Factory, not the hardcoded ones. This further separates kubectl from the core API scheme and allows better composition.
Change NamePrinter to use RESTMapper (previously it was hardcoding those conversions). This means that we now return plural resource names (`pods/foo`) but is correct once aliases and shortnames start being returned by the mapper.
This is a prerequisite for server side get, but is pure refactor (contains no new features).

Add storage.k8s.io/v1 API
v1 API is direct copy of v1beta1 API. This v1 API gets installed and exposed in this PR, I tested that kubectl can create both v1beta1 and v1 StorageClass.
~~Rest of Kubernetes (controllers, examples,. tests, ...) still use v1beta1 API, I will update it when this PR gets merged as these changes would get lost among generated code.~~ Most parts use v1 API now, it would not compile / run tests without it.
**Release note**:
```
Kubernetes API storage.k8s.io for storage objects is now fully supported and is available as storage.k8s.io/v1. Beta version of the API storage.k8s.io/v1beta1 is still available in this release, however it will be removed in a future Kubernetes release.
Together with the API endpoint, StorageClass annotation "storageclass.beta.kubernetes.io/is-default-class" is deprecated and "storageclass.kubernetes.io/is-default-class" should be used instead to mark a default storage class. The beta annotation is still working in this release, however it won't be supported in the next one.
```

The factory knows all possible types, and should abstract the process of

deprecate and disconnect --output-version
For at least two releases, there haven't been multiple versions of API groups and we don't plan to support conversions in commands other than `kubectl convert`. This disconnects the `--output-version` option to be consistent with conversion agnostic command before it becomes an issue.
@kubernetes/sig-cli-pr-reviews @fabianofranz @smarterclayton
```release-note
`--output-version` is ignored for all commands except `kubectl convert`. This is consistent with the generic nature of `kubectl` CRUD commands and the previous removal of `--api-version`. Specific versions can be specified in the resource field: `resource.version.group`, `jobs.v1.batch`.

Add `kubectl attach` support for multiple types
To address this issue: https://github.com/kubernetes/kubernetes/issues/24857
the new `kubectl attach` will contain three scenarios depend on args:

2. `kubectl attach TYPE NAME` : if two arguments provided, we assume first one is resource we [supported](4770162fd3/pkg/kubectl/cmd/util/factory_object_mapping.go (L285)), the second resource's name.
3. `kubectl attach TYPE/NAME` : one argument provided and arg[0] must contain `/`, ditto

Add option to set a service nodeport
**Release note**:
```release-note
Add kubectl --node-port option for specifying the service nodeport
```
This patch adds the option to set a nodeport when creating a NodePort
service. In case of a port allocation error due to a specified port
being out of the valid range, the error now includes the valid
range. If a `--node-port` value is not specified, it defaults to zero, in
which case the allocator will default to its current behavior of
assigning an available port.
This patch also adds a new helper function in `cmd/util/helpers.go` to
retrieve `Int32` cobra flags.
**Example**
```
# create a nodeport service with an invalid port
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=1
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid
value: 1: provided port is not in the valid range. Valid ports range
from 30000-32767
# create a nodeport service with a valid port
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
service "mynodeport" created
# create a nodeport service with a port already in use
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid value: 3000: provided port is already allocated

being out of the valid range, the error now includes the valid
range. If a `--node-port` value is not specified, it defaults to zero, in
which case the allocator will default to its current behavior of
assigning an available port.
This patch also adds a new helper function in `cmd/util/helpers.go` to
retrieve `Int32` cobra flags.
**Example**
```
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=1
The Service "mynodeport" is invalid: spec.ports[0].nodePort: Invalid
value: 1: provided port is not in the valid range. Valid ports range
from 30000-32767
$ kubectl create service nodeport mynodeport --tcp=8080:7777 --node-port=30000
service "mynodeport" created
$ oc describe service mynodeport
Name: mynodeport
Namespace: default
Labels: app=mynodeport
Selector: app=mynodeport
Type: NodePort
IP: 172.30.81.254
Port: 8080-7777 8080/TCP
NodePort: 8080-7777 30000/TCP

Unwrap aggregates of size 1 when writing errors
Our special error logic was being defeated by aggregates.
Also, only use aggregate in get when we actually are dealing with
multiple errors.
@kubernetes/kubectl
For other kubectl reviewers - no one should use an aggregate unless you are ranging over a list, and even then ask yourself whether you really care about returning all errors.

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)

add resource filter handling before printing
**Release note**:
```release-note
release-note-none
```
Resources are currently filtered (in order to prevent printing) at print
time in their HumanReadablePrinter handlers. This design makes it not
possible to filter objects when they are printed using any other
printer, such as YAML, JSON, or the NamePrinter.
This patch removes any filters previously added at the printer level for
pods and adds a way to define resource-specific filters before they are
sent to a printer handler. A woking filter handler for pods has also been
implemented.
Filters affect resources being printed through the HumanReadablePrinter,
YAML, JSON, and `--template` printers.

Behave gracefully in kubectl if /version returns 404
Fixes https://github.com/kubernetes/kubernetes/issues/32679.
It's only about caching the swagger spec here. So it's safe to fall back to non-caching mode and continue.
This commit moves away from using a global variable for default
configuration checking, and instead exposes a method on LoadingRules to
determine whether a particular restclient.Config should be considered
"default". This allows kubectl to provide its own defaults (the same
as before, KUBERNETES_MASTER and the static localhost:8080 values) while
allowing other clients to avoid defining them.
In-cluster config defaulting is now easier to read.

Handle Stream() errors consistently in restclient
We should be following the same rules for Stream() as the normal body
request flow.
Also add slightly more output on a server error - in the future we may
want to clean this up but it's potentially hiding bad responses.

Optimise the DefaultGenerators function

add ClientSet to factory to remove non-generated client
We should move to using generated clients in the `kubectl` client. We should really move to generated external clients, but this at least moves away from using manually created clients.
@fabianofranz @mfojtik When I complete this work (move the other commands and eliminate the old API), this will ripple downstream.

make swaggerschema agnostic about which version to use
`Factory.SwaggerSchema` was reliant on having a non-generated client bits filled in so that it could get the adapted client it wanted. There's no need since discovery ignores configured GroupVersions. This eliminates the unneeded dependency.
We should be following the same rules for Stream() as the normal body
request flow.
Also add slightly more output on a server error - in the future we may
want to clean this up but it's potentially hiding bad responses.
This changes clientcmd to skip the default cluster, but preserves the
behavior in kubectl. This prevents the possibility of an administrator
misconfiguration in kubelet or other server component from allowing a
third party who can bind to 8080 on that host from potentially
impersonating an API server and gaining root access.

remove duplicate errors from aggregate error outputs
release-label-none
Duplicate error messages are sometimes shown when displaying aggregate errors:
`$ kubectl label pod/database-1-fn0r7 qwer1345%$$#=self`
```
* metadata.labels: Invalid value: "qwer1345%5602#": name part must match the regex ([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9] (e.g. 'MyName' or 'my.name' or '123-abc')
* metadata.labels: Invalid value: "qwer1345%5602#": name part must match the regex ([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9] (e.g. 'MyName' or 'my.name' or '123-abc')

```
This patch removes any duplicate messages (adjacent or not) that appear in the final list of errors.
