Move the common test functions from cmd_test.go to cmd/testing/fake.go
**What this PR does / why we need it**:
This is so that we can use NewAPIFactory() from cmd/set/*test.go
Up until now we would get a import loop error.
This commit also adds a basic unit test case for cmd/set/set_image.go
**Which issue this PR fixes**
partial #34592

This particular message isn't usually important, so demote it to glog.

Improvements to CLI usability and maintainability
Improves `kubectl` from an usability perspective by
1. Fixing how we handle terminal width in help. Some sections like the flags use the entire available width, while others like long descriptions breaks lines but don't follow a well established max width (screenshot below). This PR adds a new responsive writer that will adjust to terminal width and set 80, 100, or 120 columns as the max width, but not more than that given POSIX best practices and recommendations for better readability.
2. Adds our own normalizers for long descriptions and cmd examples which allows us better control about how things like lists, paragraphs, line breaks, etc are printed. Features markdown support. Looks like `templates.LongDesc` and `templates.Examples` instead of `dedent.Dedend`.
3. Allows simple reordering and reuse of help and usage sections.
3. Adds `verify-cli-conventions.sh` which intends to run tests to make sure cmd developers are using what we propose as [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md). Just a couple simple tests for now but the framework is there and it's easy to extend.
4. Update [kubectl conventions](https://github.com/kubernetes/kubernetes/blob/master/docs/devel/kubectl-conventions.md) to use our own normalizers instead of `dedent.Dedent`.

attempt to use discovery RESTMapper and fallback if we can't
Updates `kubectl` to always attempt discovery regardless of server version. This is needed to extension servers.

Update run flags to point to generators docs
@janetkuo you've requested that in https://github.com/kubernetes/kubernetes/pull/32484#issuecomment-246840562 I'm opening this PR but like you I don't like the length of the descriptions already. The other problem with this is that there's not clean docs for a user to figure out what the generators are. I've stumbled upon this several times and I always found myself looking into the code :/ How about adding new flag/subcommand that will give you more information about generators and we'd move all those `--restart` and `--generator` information into specific generator info and present at the top level only general information?

Add 'kubectl set resources'
Add "kubectl set resources" for easier updating container memory/cpu limits/requests (for pods or resources with pod templates).
**Usage**
`kubectl set resources (-f FILENAME | TYPE NAME) ([--limits=LIMITS & --requests=REQUESTS])`
**Examples**
Set a deployments nginx container cpu limits to "200m and memory to "512Mi"
`kubectl set resources deployment nginx -c=nginx --limits=cpu=200m,memory=512Mi`
Set the limit and requests for all containers in nginx
`kubectl set resources deployment nginx --limits=cpu=200m,memory=512Mi --requests=cpu=100m,memory=256Mi`
Print the result (in yaml format) of updating nginx container limits from a local, without hitting the server
`kubectl set resources -f path/to/file.yaml --limits=cpu=200m,memory=512Mi --local -o yaml`
Remove limits on containers in nginx
`kubectl set resources deployment nginx --limits=cpu=0,memory=0`

Ref: https://github.com/kubernetes/kubernetes/issues/21648
I squashed the commits to make rebasing easier
Change log:
- fixed a typo that caused the command to be run with kubectl set set instead of the correct kubectl set limit
- added a ResourcesWithPodTemplates to pkg/kubectl/cmd/util/factory.go
instead of hardcoding these resources move there description all in one place
- Fixing some of the flow control in kubectl set limit
- update the help info
- changed the name of ResourcesWithPodTemplates to ResourcesWithPodSpecs to more accuratly describe what it is doing
and changed the variable names to lower case to conform to go's variable naming convention
- changing the name of the command from 'set limit' to 'set resources'
- Adding the new file pkg/kubectl/cmd/set/set_resources.go
- changes to the test cases to reflect the change from 'kubectl set limit' to 'kubectl set resources'
- comment removed
- adding the man page to the git repository attempting to fix Jenkins tests
- adding the user guide
- fixed a few typos

- changed limits/requests to requests/limit
- changing ResourcesWithPodSpec
- updated generated docs and removed whitespace
- change priint on success message from "resource limits/requests updated" to "resource requirements updated"
- minor rebasing issues - 'hack/test-cmd.sh' now passes
- cmdutil.PrintSuccess added another argument
- fixing mungedocs failure
- removed whitespace from hack/make-rules/test-cmd.sh and an erroneous entry from pkg/cloudprovider/providers/openstack/MAINTAINERS.md
- fixed typo in Short: field of the cobra command
- rebased
- Creating a new factory in the ResourcesWithPodSpecs() so that the testing will pass
- changing ResourcesWithPodSpecs, it doesn't need to be a method of factory

Merge string flag into util flag
Continuing my work on https://github.com/kubernetes/kubernetes/issues/15634
This refactoring is expected to be completely finished and then I will add a verify scripts in `hack`
There is a usage of options.Err in a Printf, but this option is never set.
This patch passes the stderr into the command and assigns the option correctly.

remove call to compinit in zsh completion output
**Release note**:
```release-note
release-note-none
```
Fixes: https://github.com/kubernetes/kubernetes/issues/32029
Fixes:
https://github.com/kubernetes/kubernetes/issues/27538#issuecomment-238574035
The zsh completion output makes a call to "compinit" which causes the
zsh completion system to re-initialize every time `<root_cmd> completion zsh`
is sourced, overwriting any settings already applied to other commands.
This in-turn caused other commands' completions to break (such as git,
gcloud, vim) causing an error "function definition file not found" to
be returned any time a tab-completion was attempted.
This patch removes the call to `compinit` in the zsh completion output,
causing no behavioral changes to the existing `completion` command, but
fixing any issues that were caused after sourcing its output.

return warning on empty list result in kubectl get
**Release note**:
```release-note
NONE
```
The current default behavior of `kubectl get` is to return an empty
output when there are no resources to display. This patch improves
usability by returning a warning through stderr in the case of an empty
list.
##### Before
`$ kubectl get pods`
- *empty output*
##### After
`$ kubectl get pods`
```
There are no resources to display.
```
