Verify and update client-go staging area for every PR
We need to keep the staging area up-to-date to prevent PRs from breaking client-go.
It's marked as "WIP" because we need to decide the [versioning strategy](https://github.com/kubernetes/client-go/issues/9) for client-go first. This PR contains breaking changes for client-go.
This is blocking #29934 and potentially #34441

attempt to use discovery RESTMapper and fallback if we can't
Updates `kubectl` to always attempt discovery regardless of server version. This is needed to extension servers.
Add a way to set resource limits/requests on running pods
Ref: https://github.com/kubernetes/kubernetes/issues/21648
I squashed the commits to make rebasing easier
Change log:
- fixed a typo that caused the command to be run with kubectl set set instead of the correct kubectl set limit
- added a ResourcesWithPodTemplates to pkg/kubectl/cmd/util/factory.go
instead of hardcoding these resources move there description all in one place
- Fixing some of the flow control in kubectl set limit
- update the help info
- changed the name of ResourcesWithPodTemplates to ResourcesWithPodSpecs to more accuratly describe what it is doing
and changed the variable names to lower case to conform to go's variable naming convention
- changing the name of the command from 'set limit' to 'set resources'
- Adding the new file pkg/kubectl/cmd/set/set_resources.go
- changes to the test cases to reflect the change from 'kubectl set limit' to 'kubectl set resources'
- comment removed
- adding the man page to the git repository attempting to fix Jenkins tests
- adding the user guide
- fixed a few typos
- typo in hack/cmd-test.sh
- implamenting suggestions for command help text
- adding the dry-run flag
- removing the "remove" option in favor of zeroing out request/limits in order to remove them
- changed limits/requests to requests/limit
- changing ResourcesWithPodSpec
- updated generated docs and removed whitespace
- change priint on success message from "resource limits/requests updated" to "resource requirements updated"
- minor rebasing issues - 'hack/test-cmd.sh' now passes
- cmdutil.PrintSuccess added another argument
- fixing mungedocs failure
- removed whitespace from hack/make-rules/test-cmd.sh and an erroneous entry from pkg/cloudprovider/providers/openstack/MAINTAINERS.md
- fixed typo in Short: field of the cobra command
- rebased
- Creating a new factory in the ResourcesWithPodSpecs() so that the testing will pass
- changing ResourcesWithPodSpecs, it doesn't need to be a method of factory

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
$ kubectl describe service mynodeport
Name: mynodeport
Namespace: default
Labels: app=mynodeport
Selector: app=mynodeport
Type: NodePort

Allow empty annotation values
Related downstream issue: https://github.com/openshift/origin/issues/11175
**Release note**:
```release-note
release-note-none
```
Annotations with empty values can be used, for example, in diagnostics
logging. This patch removes the client-side check for empty values in
an annotation key-value pair.
**Before**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
error: invalid annotation format: node-selector=
```
**After**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
pod "zookeper-1" annotated
```
```
$ kubectl get po/zookeeper-1 --template='{{.metadata.annotations}}'
map[... node-selector: test-label:test]
```

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.
