Forgiveness library changes
**What this PR does / why we need it**:
Splited from #34825, contains library changes that are needed to implement forgiveness:
1. ~~make taints-tolerations matching respect timestamps, so that one toleration can just tolerate a taint for only a period of time.~~ As TaintManager is caching taints and observing taint changes, time-based checking is now outside the library (in TaintManager). see #40355.
2. make tolerations respect wildcard key.
3. add/refresh some related functions to wrap taints-tolerations operation.
**Which issue this PR fixes**:
Related issue: #1574
Related PR: #34825, #39469
~~Please note that the first 2 commits in this PR come from #39469 .~~
**Special notes for your reviewer**:
~~Since currently we have `pkg/api/helpers.go` and `pkg/api/v1/helpers.go`, there are some duplicated periods of code laying in these two files.~~
~~Ideally we should move taints-tolerations related functions into a separate package (pkg/util/taints), and make it a unified set of implementations. But I'd just suggest to do it in a follow-up PR after Forgiveness ones done, in case of feature Forgiveness getting blocked to long.~~
**Release note**:
```release-note
make tolerations respect wildcard key

genericapiserver: cut off more dependencies – episode 3

This is the first step to get `apiserver_test.go` and `watch_test.go` in `pkg/genericapiserver/endpoints` cutoff from k8s.io/kubernetes dependencies.
After this we have to sync client-go and then "episode 4" can go in.

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

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.

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).

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.

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 kubectl Stratigic Merge Patch compatibility
As @smarterclayton pointed out in [comment1](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290820) and [comment2](https://github.com/kubernetes/kubernetes/pull/35647#pullrequestreview-8290847) in PR #35647,
we cannot assume the API servers publish version and they shares the same version.
This PR removes all the calls of GetServerSupportedSMPatchVersion().
Change the behavior of `apply` and `edit` to:
Retrying with the old patch version, if the new version fails.
Default other usage of SMPatch to the new version, since they don't update list of primitives.

make kubectl create --edit iterate
`kubectl create --edit` is broken after #36148 merged.
`kubectl create --edit` will fail when a manifest that contains multiple resources.
I guess the root cause is that dynamic typer doesn't support a list of resources currently.
This PR makes `kubectl create --edit` iterate again as `kubectl create`.

V2resource fixes
when using kubectl set resources it resets all resource fields that are not being set.
for example
$ kubectl set resources deployments nginx --limits=cpu=100m
followed by
$ kubectl set resources deployments nginx --limits=memory=256Mi
would result in the nginx deployment only limiting memory at 256Mi with the previous
limit placed on the cpu being wiped out. This behavior is corrected so that each invocation
only modifies fields set in that command and changed the testing so that the desired behavior
is checked.
Also a typo:
you must specify an update to requests or limits or (in the form of --requests/--limits)
corrected to
you must specify an update to requests or limits (in the form of --requests/--limits)
Implemented both the dry run and local flags.
Added test cases to show that both flags are operating as intended.
Removed the print statement "running in local mode" as in PR#35112
The original PR associated with these fixes where reverted due to causing a flake in hack/make-rules/test-cmd.sh, I gave the 'kubectl set resources' tests there own deployment and set the terminationGracePeriodSeconds to 0 and have run test-cmd.sh for hours without hitting the flake

kubectl: add less verbose version
The kubectl version output is very complex and makes it hard for users
and vendors to give actionable information. For example during the
recent Kubernetes 1.4.3 TLS security scramble I had to write a one-liner
for users to get out the version number to give to figure out if they
are vulnerable:
```
$ kubectl version | grep -i Server | sed -n 's%.*GitVersion:"\([^"]*\).*%\1%p'
```
Instead this patch outputs simply output by default
```
./kubectl version
Client Version: v1.4.3
Server Version: v1.4.3
```
Adding the `--verbose` flag will output the old format.

Fix handling lists in kubectl convert
Fixes https://github.com/kubernetes/kubernetes/issues/36722
When handling multiple objects in `kubectl convert` (for example in `kubectl convert -f .` with multiple files in current directory) the objects must be managed as a list instead of individually, otherwise `-o yaml|json` will generate invalid format (just multiple json/yaml objects concatenated) which can't be fed to `kubectl create` like in `kubectl convert -f . | kubectl create -f -`.

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.
Fixes#35163, #32398
