Cli: Add "-r, --noprompt" flag to sfdx plugins:install command

[ImJohnMDaniel]

Is your feature request related to a problem? Please describe.
If I setup a Jenkins CI build and specify the "sfdx" as a custom tool, I would also want to install custom plugins that I have created to aid in the build process. Currently, there is no way to execute sfdx plugins:install foo-bar without confirming the plugin installation since it is not digitally signed. Because of this, I cannot use the Jenkins Custom Tool plugin when I need specific custom SFDX CLI plugins as well.

What are you trying to do
I need a way to dynamically setup the SFDX CLI and plugins that I want to install via the Jenkins custom tool option.

Describe the solution you'd like
I would like a "-r, --noprompt" flag be added to plugins:install command so that I can automate on my CI builds the installation of the plugin after the installation of the SFDX CLI itself.

Describe alternatives you've considered
I could manually install the SFDX CLI and the plugins on the Jenkins server and not utilize the "custom tool" option, but then I would not be able to dynamically spin up slave Jenkins instances as needed.

Hello @ImJohnMDaniel
A workarround to this issue:
echo y | sfdx plugins:install sfpowerkit

@genoud -- Thanks for the tip. That is exactly what we ended up doing and what led to this feature request. ;-)

@genoud That saved my life - thanks!

@ImJohnMDaniel there's two other more elegant options I'd suggest.

1. if you're doing other npm installs for your CI, add your plugins as a dependency and then plugins:link them from the node_modules folder (when using plugins:link you don't get the code-signing check).
2. add those plugins to your unsignedPluginAllowList.json. More info about that file here here: https://developer.salesforce.com/blogs/2017/10/salesforce-dx-cli-plugin-update.html

1 is probably the better option for CI because your CI may get some npm-caching benefits and more granular control of which version of the plugin you're running.

@mshanemc, I'm on windows and this may be a more windows-specific problem but I've found that when I have a plugin linked then execution of all commands is slower as it seems to re-compile/process the linked plugins every time. I have never dug into the root cause, I just don't leave plugins linked as much as I used to.

(edited as I realized that solution was already provided above)

@mshanemc -- Apologies, I did not see your earlier comment from Dec 4, 2020. I am aware of both options that you are referring to in that post and neither are an option for me.

Just curious, why are you designating this as "wontfix". I would expect this to be an extremely small LOE -- Simply add the flag and put in an if/then statement.
