Allows kubectl create -f to filter by selector.
From #32544.
The underlying `seletor` infrastructrue was implemented by #32599. The test is basically copy-paste of the corresponding test for `kubectl apply -f -l`.
```release-note
kubectl create now accepts the label selector flag for filtering objects to create

Will open the data element named `bar` in the `ConfigMap` named `foo` in `$EDITOR`, the edited contents are then updated back to the config map.

move pkg/fields to apimachinery
Purely mechanical move of `pkg/fields` to apimachinery.
Discussed with @lavalamp on slack. Moving this an `labels` to apimachinery.
@liggitt any concerns? I think the idea of field selection should become generic and this ends up shared between client and server, so this is a more logical location.
This patch adds a new `EnsurePrintHeaders` method to the
HumanReadablePrinter `ResourcePrinter`, which allows headers to be
printed in cases where multiple lists of the same resource are printed
consecutively, but are separated by non-printer related information.

Make kubectl proxy accept empty path
**What this PR does / why we need it**:
The kubectl proxy previously returned 403 Forbidden: Unauthorized when receiving a request from e.g. "curl localhost:8001" or "curl localhost:8001/". The previous DefaultPathAcceptRE regex was wrong as it assumed the path in this case would be "/" (but it is actually "").
After someone runs kubectl proxy and tries accessing it with curl, they will probably just try hitting localhost:8001 (which returns an "Unauthorized" response) instead of say localhost:8001/api (which returns a proper response from the API server). Also, whoever previously modified the DefaultPathAcceptRE regex was obviously expecting the regex to accept requests for localhost:8001/

Its unnecessary to print the message when the user asked for it.
We should only show a msg (error) when we didn't do what they asked.
Also showing this in a "kubectl run" is bad because it then
gets appended to the user's output and they would then have to strip
it off if they want to use the output in some follow-on processing.

Pass addressable values to DeepCopy
Extracted from https://github.com/kubernetes/kubernetes/pull/35728
These are the places we are currently calling DeepCopy incorrectly, and we need to fix, even if we don't pick up the changes to DeepCopy in #35728:
* creating a new cloner means we have no generated functions registered
* passing non-addressable values doesn't pick up generated deep copy functions, and forces us into reflective mode

fix local resource output when `-f` not specified
**Release note**:
```release-note
release-note-none
```
`kubectl set image` does not have a `--dry-run` option. Although it offers a
`--local` flag, it does not support server request, limiting input to that of stdin
or that of a local file.
This patch adds a `--dry-run` option to the `kubectl set image` command,
allowing for resources from the server to be selected, without making any
mutations.

Remove duplicate describer errs
Downstream issue https://github.com/openshift/origin/issues/11846
**Release note**:
```release-note
release-note-none
```
The `describe` command iterates through a list of infos received from
the server and aggregates a list of errors while attempting to call each
resource's respective describer. When a resource exists, but does not
have a describer set, such as `Event`, the `describe` command outputs
the same error `error: no description has been implemented for "Event"`
for each info.
```
$ kubectl describe events
no description has been implemented for "Event"
no description has been implemented for "Event"
no description has been implemented for "Event"
no description has been implemented for "Event"

add resource prefix to multiple items w/ same kind
**Release note**:
```release-note
release-note-none
```
This patch ensures that a resource prefix is added to multiple items of
the same kind, when using `kubectl get all`. Before, a prefix was added only
when a single item was returned on `kubectl get all`, but ignored if only a
single resource kind existed but multiple items for that kind were
returned.
**Example**
```
$ kubectl get all
No resources found.
$ kubectl create service loadbalancer testsvc1 --tcp=8080
$ kubectl get all
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
svc/testsvc1 172.30.119.220 172.46.100.155,172.46.100.155 8080/TCP 1h
$ kubectl create service loadbalancer testsvc2 --tcp=8081
$ kubectl get all
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
svc/testsvc1 172.30.119.220 172.46.100.155,172.46.100.155 8080/TCP 1h
svc/testsvc2 172.30.241.197 172.46.164.158,172.46.164.158 8081/TCP 1h

RESTMapping method can now rely on RESTMappings by passing versions parameter and taking the first match found by RESTMappings method. In addition
a UT that test the new method has been added.
The only change in logic to what was before is when calling RESTMapping
we search all defaultGroupVersion as opposed to just one when no mapping was found for provided versions.

kubectl top pod|node should handle when Heapster is somewhere else
OpenShift runs Heapster on HTTPS, which means `top node` and `top pod`
are broken because they hardcode 'http' as the scheme. Provide an
options struct allowing users to specify `--heapster-namespace`,
`--heapster-service`, `--heapster-scheme`, and `--heapster-port` to the
commands (leveraging the existing defaults).

add some help info about the 'all' arg
**What this PR does / why we need it**:
There is an arg named "all" in the get command, we can use it like "kubectl get all". But we can get nothing about this arg in the help description. Users may not know how to use it without looking into the source code. So here I'm going to add some description about this arg.
**Which issue this PR fixes**
We discussed about this in
In pkg/kubectl/cmd/get.go there is a confused arg named "all" [#37533](https://github.com/kubernetes/kubernetes/issues/37533)
This patch ensures that a resource prefix is added to multiple items of
the same kind, when using `oc get all`. Before, a prefix was added only
when a single item was returned on `oc get all`, but ignored if only a
single resource kind existed but multiple items for that kind were
returned.

When --grace-period=0 is provided, wait for deletion
The grace-period is automatically set to 1 unless --force is provided, and the client waits until the object is deleted.
This preserves backwards compatibility with 1.4 and earlier. It does not handle scenarios where the object is deleted and a new object is created with the same name because we don't have the initial object loaded (and that's a larger change for 1.5).
Fixes#37117 by relaxing the guarantees provided.
```release-note
When deleting an object with `--grace-period=0`, the client will begin a graceful deletion and wait until the resource is fully deleted. To force deletion, use the `--force` flag.
