If "Allocatable" is used to a node total memory size, under high memory pressure or pre-reserved memory value is bigger, the "MEMORY%" can be bigger than 100%.
For suppressing the confusing, add a option to show node real memory usage based on "Capacity".

* Basic scaffolding for kubectl events command
* Simple implementation of 'kubectl events'
* Print event fields
Borrowing code from 'kubectl describe'
* Sort events before printing
* Make output more like 'kubectl get events'
Print namespace if fetching from all
* Refactor: extract print functions
To make it easier to add watch function next.
* Implement watch for new events
Run the list function same as before, so those events come out in order,
then watch from the ResourceVersion after the last event.
* Clear up some lint warnings
* Update description and example text
* refactor: introduce a listOptions variable
* Implement --for option
splitResourceTypeName() function borrowed from cli-runtime because we
need similar behaviour to Builder.ResourceNames(), but applying to
Event.InvolvedObject.
* Add kubectl/pkg/cmd/events to vendor/modules.txt
* Add back cmdutil.Factory
Needed in NewCmdAlpha to construct the 'events' command

Flags represents the inputs from the CLI; options are what the running
command needs. This structure parallels the 'wait' command, and should
be easier to write tests for.

* Add some parameters to usage string

* Do only one of list or watch
We tried to print the list first then start a watch after the last
event, but sometimes the server will return "watch is too old" on that
ResourceVersion.
Instead, if we need to watch just start it from the beginning.

arrives.

This commit teaches the completion function to repeat resource names
when supported by the command. The logic checks if a resource name
has already been specified by the user and does not include it again
when repeating the completion.
For example, the get command can receive multiple pods names, therefore
with this commit we have:
kubectl get pod pod1 [tab]
will provide completion of pod names again, but not show 'pod1' since
it is already part of the command-line.
The improvement affects the following commands:
- annotate
- apply edit-last-applied
- apply view-last-applied
- autoscale
- delete
- describe
- edit
- expose
- get
- label
- patch
- rollout history
- rollout pause
- rollout restart
- rollout resume
- rollout undo
- scale
- taint
Note that "rollout status" only accepts a single resource name, unlike
the other "rollout ..." commands; this required the creation of a
special completion function that did not repeat just for that case.

I initially noticed a minor typo in --tty, and while fixing it,
I noticed small discrepancies in some other flags. These minor
changes should make the 'kubectl run' flag help slightly more
correct (hopefully). 🙂

This PR adds flagerror handler function to detect when flags are invalid.
Default flag handler returns status code 1. However, diff command embraces
this status code as changes are found. By overriding flag errors,
this PR shows same message with default case and returns status code 2.

Cobra adds the commands 'help', '__complete' and '__completeNoDesc'
inside rootCmd.Execute(), however, when kubectl decides if it should
lookup plugins, rootCmd.Execute() had not been called yet. Therefore,
the call to cmd.Find(cmdPathPieces) done by kubectl does not find the
commands added by Cobra. To fix this we must check for them explicitly.

Kubernetes-commit: e703b3d25377e763b117805b3d88fe7236f3ff76
It wasn't documented that InitLogs already uses the log flush frequency, so
some commands have called it before parsing (for example, kubectl in the
original code for logs.go). The flag never had an effect in such commands.
Fixing this turned into a major refactoring of how commands set up flags and
run their Cobra command:
- component-base/logs: implicitely registering flags during package init is an
anti-pattern that makes it impossible to use the package in commands which
want full control over their command line. Logging flags must be added
explicitly now, something that the new cli.Run does automatically.
- component-base/logs: AddFlags would have crashed in kubectl-convert if it
had been called because it relied on the global pflag.CommandLine. This
has been fixed and kubectl-convert now has the same --log-flush-frequency
flag as other commands.
- component-base/logs/testinit: an exception are tests where flag.CommandLine has
to be used. This new package can be imported to add flags to that
once per test program.
- Normalization of the klog command line flags was inconsistent. Some commands
unintentionally didn't normalize to the recommended format with hyphens. This
gets fixed for sample programs, but not for production programs because
it would be a breaking change.
This refactoring has the following user-visible effects:
- The validation error for `go run ./cmd/kube-apiserver --logging-format=json
--add-dir-header` now references `add-dir-header` instead of `add_dir_header`.
- `staging/src/k8s.io/cloud-provider/sample` uses flags with hyphen instead of
underscore.
- `--log-flush-frequency` is not listed anymore in the --logging-format flag's
`non-default formats don't honor these flags` usage text because it will also
work for non-default formats once it is needed.
- `cmd/kubelet`: the description of `--logging-format` uses hyphens instead of
underscores for the flags, which now matches what the command is using.
- `staging/src/k8s.io/component-base/logs/example/cmd`: added logging flags.
- `apiextensions-apiserver` no longer prints a useless stack trace for `main`
when command line parsing raises an error.

The boolean values for --dry-run have been deprecated for removal since
1.18, more than 2 releases.
The default value for --dry-run with the flag set and unspecified has
been deprecated for removal since 1.18, more than 2 releases.
Both values are now removed in this change. Any kubectl --dry-run
usage no longer accepts --dry-run=(true|false) boolean values and usage
now requires that a value of (client|server|none) is specified.

1. string is formatted as unsafe json. Since this is created on the fly;
TaintKey and Effect are formatted as a 'key=effect' instead of '{key=effect}'
eliminating unsafe json representation.
2. Adds a fail test case for the case where a taint with same key and effect is added
and removed together.

The ephemeral containers API changed in 1.22. As a result, kubectl
debug (currently) cannot create ephemeral containers in clusters prior
to 1.22.
This change causes kubectl to retry the request using the old API when
it receives a specific error message from the server.

This is no longer true as of `containerd` v1.4.0 because [0] removes `socat` dependency for port-forwarding. For lower versions of `containerd`, the error message is descriptive i.e. `"socat": executable file not found in $PATH`.

* Use deep copies in `PrepareForUpdate()`

Kubernetes-commit: 97726a50c138557522def7f753ec8581d00f0b02
This changes the `/ephemeralcontainers` subresource of `/pods` to use
the `Pod` kind rather than `EphemeralContainers`.
When designing this API initially it seemed preferable to create a new
kind containing only the pod's ephemeral containers, similar to how
binding and scaling work.
It later became clear that this made admission control more difficult
because the controller wouldn't be presented with the entire Pod, so we
updated this to operate on the entire Pod, similar to how `/status`
works.

--current-replicas is only meaningful when it's -1 or greater.
Also add an error message to clarify the range of --current-replicas. It
is unclear that --current-replicas=-1 means no precondition. This info
may be useful for programming purposes (i.e., shell scripting, etc.).

Assume the following CRDs exist (ordered by priority, the first is the highest):
- authentications.migration.k8s.io (K=Authentications, G=migration.k8s.io)
- authentications.metal3.io (K=Authentications, G=metal3.io)
- authentications.whereabouts.cni.cncf.io (K=Authentications, G=whereabouts.cni.cncf.io)
- authentications.snapshot.storage.k8s.io (K=Authentications, G=snapshot.storage.k8s.io)
In case 'kubectl explain authentications' is ran, the highest priority definition (in this case authentications.migration.k8s.io)
is returned. In case a user wants to explain authentication CRD of a different group, --api-version flag has to be set alongside
to point to a specific group and version. E.g. --api-version=metal3.io/v1
This PR allows to dismiss --api-version flag and perform a prefix check to select a resource (e.g. CRD) whose (resource, group) pair
fully prefixes requested resource. E.g. running 'kubectl explain authentications.metal3.io' will return
description of authentications.metal3.io. The same holds for optional field path.
I.e. 'kubectl explain authentications.metal3.io.spec' will return description of spec field
of authentications.metal3.io.spec. In case no resource match is found, the search falls back
to selecting the highest priority gvr that matches the resource.
In case --api-version is set, no prefix matching is performed. To cover cases
such as 'kubectl explain authentications.metal3.io --api-version=authentications.metal3.io/v1' where
fields path coincide with the resource fully specified name (to access .metal3.io field of authentications.metal3.io).
