retry GetThirdPartyGroupVersions
GetThirdPartyGroupVersions() may return a "NotFound" error if a thirdparty group is deleted in the interim between the group-discovery and the resource-discovery. This is causing e2e flakes in all tests that run kubectl, because test/e2e/thirdparty.go is creating/deleting thirdparty groups.
Fix#26425
The e2e flakes will have the following pattern:
1. the test is calling kubectl
2. error message is `Error from server: the server could not find the requested resource`
3. in the apiserver log, you should see `GET /apis/company.com/v1: (518.944µs) 404 [[kubectl/v1.3.0 (linux/amd64) kubernetes/ae28564] 104.154.110.118:46043]`

Fix panic when the namespace flag is not present
We don't set the namespace in OpenShift, so we need to check if the namespace flag is present.

fix edit on list
Fixes https://github.com/kubernetes/kubernetes/issues/20519
This reverts the implementation that removed list editing capability, but leaves its tests intact. This allows edits of lists to work, while still allowing mutation of the annotations. It does this by walking each item and building per item patches.
The current implementation will do funny things if you delete entire list entries. A followup could be written to locate the correct list item by name. Right now, it just rejects the patch because its trying to change an immutable field.

Add 'kubectl set image'
```release-note
Add "kubectl set image" for easier updating container images (for pods or resources with pod templates).
```
**Usage:**
```
kubectl set image (-f FILENAME | TYPE NAME) CONTAINER_NAME_1=CONTAINER_IMAGE_1 ... CONTAINER_NAME_N=CONTAINER_IMAGE_N
```
**Example:**
```console
# Set a deployment's nginx container image to 'nginx:1.9.1', and its busybox container image to 'busybox'.
$ kubectl set image deployment/nginx busybox=busybox nginx=nginx:1.9.1
# Update all deployments' nginx container's image to 'nginx:1.9.1'
$ kubectl set image deployments nginx=nginx:1.9.1 --all
# Update image of all containers of daemonset abc to 'nginx:1.9.1'
$ kubectl set image daemonset abc *=nginx:1.9.1
# Print result (in yaml format) of updating nginx container image from local file, without hitting the server
$ kubectl set image -f path/to/file.yaml nginx=nginx:1.9.1 --local -o yaml
```
I abandoned the `--container=xxx --image=xxx` flags in the [deploy proposal](https://github.com/kubernetes/kubernetes/blob/master/docs/proposals/deploy.md#kubectl-set) since it's much easier to use with just KEY=VALUE (CONTAINER_NAME=CONTAINER_IMAGE) pairs.
