Provide a cleaner help output which would make it easier to use

Please update the help responses to be context sensitive and remove currently displayed info that is irrelevant. The information supplied is overwhelming to most, it would not be so overwhelming if it only showed information relevant to the current help request.

The bold info below is an example of what I believe to be irrelevant, but maybe I'm wrong and there are edge use cases.

e.g.:

> C:\>clist -help
> Chocolatey v0.10.13
> List/Search Command
>
> Chocolatey will perform a search for a package local or remote. Some
> may prefer to use `clist` as a shortcut for `choco list`.
>
> NOTE: 100% compatible with older Chocolatey client (0.9.8.x and below)
> with options and switches. In most cases you can still pass options
> and switches with one dash (`-`). For more details, see
> the command reference (`choco -?`).
>
> Usage
>
> choco search []
> choco list []
> clist []
>
> Examples
>
> choco list --local-only
> choco list -li
> choco list -lai
> choco list --page=0 --page-size=25
> choco search git
> choco search git --source="'https://somewhere/out/there'"
> choco search bob -s "'https://somewhere/protected'" -u user -p pass
>
> NOTE: See scripting in the command reference (`choco -?`) for how to
> write proper scripts and integrations.
>
>
> Exit Codes
>
> Exit codes that normally result from running this command.
>
> Normal:
> - 0: operation was successful, no issues detected
> - -1 or 1: an error has occurred
>
> Enhanced:
> - 0: operation was successful, no issues detected
> - -1 or 1: an error has occurred
> - 2: no results (enhanced)
>
> NOTE: Starting in v0.10.12, if you have the feature 'useEnhancedExitCodes'
> turned on, then choco will provide enhanced exit codes that allow
> better integration and scripting.
>
> If you find other exit codes that we have not yet documented, please
> file a ticket so we can document it at
> https://github.com/chocolatey/choco/issues/new/choose.

Start by examining how help output is generated for `choco list`, `choco search`, and the `clist` alias. Compare the displayed sections with the command and options being requested, then define which information is relevant for each context and verify that the resulting help is less overwhelming without removing needed usage details.
