allow higher burst for discovery
Discovery makes a lot of consecutive (maybe someday parallel) calls. One for every group and another for every version. Add a few CRDs and it's pretty easy to get to 50 calls.
This targets the burst on kubectl's discovery client only.

Builds on https://github.com/kubernetes/kubernetes/pull/61912 (original commit is there for credit/blame)
This keeps all the updates to the scaler building and all the test and reaper cleanup. It just keeps a fake job scaler around for a different command path and the reaper.

kubectl: make error with resource list prettier
**What this PR does / why we need it**:
Previously, running commands like `kubectl get` with no further
arguments would print a list of valid resource types with an error
messages formatted like so:
<snip>
* serviceaccounts (aka 'sa')
* services (aka 'svc')
* statefulsets (aka 'sts')
* storageclasses (aka 'sc')error: Required resource not specified.
Use "kubectl explain <resource>" for a detailed description of that resource (e.g. kubectl explain pods).
See 'kubectl get -h' for help and examples.
This commit adds extra spacing so it now looks pretty:
<snip>
* serviceaccounts (aka 'sa')
* services (aka 'svc')
* statefulsets (aka 'sts')
* storageclasses (aka 'sc')
error: Required resource not specified.
Use "kubectl explain <resource>" for a detailed description of that resource (e.g. kubectl explain pods).

Restore show-kind function when printing multiple kinds
Fixes#61979
* Makes the human readable printer work off the options given to it for displaying kind
* Simplifies get.go to pass showkind/kind options into the printer rather than doing conditional fixup afterward
```release-note
kubectl: restore the ability to show resource kinds when displaying multiple objects
```
Approval for CSRs is only needed once. If the CSR is already approved or
denied we can skip updating it. Add a `--force` flag that allows the
existing behavior for when a user has a specific need to update the CSR.
This is backwards compatible with the intended use of the conditions,
although it's possible some users are depending on the status being
updated. It makes bulk approval as an admin much faster for scripting.

kubectl: fix a panic when createGeneratedObject failed
**What this PR does / why we need it**:
This PR fixed two bugs in the `kubectl run` command.
The first commit fixed a panic that can be reproduced with the following two commands:
```bash
kubectl run --image=alpine hello -- sleep 1d
kubectl run --image=alpine --stdin --tty --attach hello -- /bin/sh
```
When the panic happens, the stack trace is as the following:
```
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x12f92e6]
goroutine 1 [running]:
k8s.io/kubernetes/pkg/kubectl/cmd.RunRun(0x1890d20, 0xc4207f6210, 0x184e700, 0xc42000c010, 0x184e720, 0xc42000c018, 0x184e720, 0xc42000c020, 0xc42052ef00, 0xc42054f980, ...)
/home/star/go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/pkg/kubectl/cmd/run.go:328 +0x10b6
k8s.io/kubernetes/pkg/kubectl/cmd.NewCmdRun.func1(0xc42052ef00, 0xc42054f980, 0x2, 0x8)
/home/star/go/src/k8s.io/kubernetes/_output/local/go/src/k8s.io/kubernetes/pkg/kubectl/cmd/run.go:105 +0x144
...
```
The reason for the panic is that the original code didn't handle the error returned by `createGeneratedObject` correctly. See https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/run.go#L281
If the function `createGeneratedObject` fails, the returned `runObject` will be `nil`. At https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/run.go#L328 a nil pointer dereference will happen.
The second problem this PR fixed is a resource leak if both `--rm` and `--expose` flags are provided. The original code used a map (https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/run.go#L280) to trace the created objects. But at https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/run.go#L296 the code will overwrite the previously created object with the same key. So at https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/run.go#L348 only the service will be deleted. The deployment will be left behind.

Ensure reasons end up as comments in kubectl edit.
**What this PR does / why we need it**:
This PR helps making sure that all text in the header of the file is prefixed with `#` when using `kubectl edit` to fix schema validation errors. The problem is best described with an example:
*Before:*
```yaml
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
#
# mycrd "example-cr" was not valid:
# * []: Invalid value: map[string]interface {}{"apiVersion":"example.com/v1alpha1", "kind":"MyCRD", "metadata":map[string]interface {}{"clusterName":"", "creationTimestamp":"2018-03-09T16:16:41Z", "name":"example-cr", "namespace":"default", "resourceVersion":"12399", "selfLink":"", "uid":"4089f5bd-23b5-11e8-a33f-42010aa40081", "generation":0}, "spec":map[string]interface {}{"size":-1}}: validation failure list:
spec.size in body should be greater than or equal to 1
#
apiVersion: example.com/v1alpha1
kind: MyCRD
```
This obviously won't be accepted as input, the user having to manually add a `#` to the line in the header.
*After:*
```yaml
# Please edit the object below. Lines beginning with a '#' will be ignored,
# and an empty file will abort the edit. If an error occurs while saving this file will be
# reopened with the relevant failures.
#
# mycrd "example-cr" was not valid:
