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`

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.

Make kubectl label and annotate more consistent
**What this PR does / why we need it**:
This makes the label and annotate cmd files more consistent which should help with code maintenance.
Some of the main changes:
- add dryrun to annotate (can push this in a different PR if requested)
- use Complete(), Validate() and RunX()
- don't place dynamic variables in the options (only user options and args)
- call the NewBuilder() in the Run function.
**Which issue this PR fixes**
fixes#34151
**Special notes for your reviewer**:
Note: you *can* now diff the two files and the changes make sense.
**Release note**:
```release-note
kubectl annotate now supports --dry-run
