`sls plugin install` failing

[TylerSustare]

This is a Bug Report

Description

• What went wrong?
  I wanted to install a serverless plugin through the CLI $ sls plugin install serverless-express but was met with an error Serverless command "plugin install serverless-express" not found. Did you mean "uninstall"? Run "serverless help" for a list of all available commands.
• What did you expect should have happened?
  I expected based on the following that I could use the sls command line to install a plugin. I normally just install by adding it to my serverless.yml and using, but I gave this a try for the first time and it wasn't as I expected

Ahh I see what I did wrong. I searched for plugins with $ sls plugin list | grep serverless-express I didn't use $ sls plugin search --query express.

The plugin search command tells you that you should

To install a plugin run 'serverless plugin install --name plugin-name-here'

It will be automatically downloaded and added to your package.json and serverless.yml file

When I did $ sls plugin install --name serverless-express it worked like a charm.

I'll be closing this issue and opening up a feature request for the $ sls plugin install utility

[TylerSustare]

I just decided to make a PR for this instead of opening a feature request.

@TylerSustare please do open an issue for your feature request 😊 ... I'm still not sure what the feature is. The title here made me think it's a bug.
