sls create: Install missing plugins automatically

Use case description

The nice thing about Serverless Framework is the dev experience. sls create / sls deploy.

But if the author has used a plugin, and you try to deploy it, you get something like this:

Serverless plugin "serverless-step-functions" not found. Make sure it's installed and listed in the "plugins" section of your serverless config file.

Then you have to Google to find out you need to run something like:

sls plugin install -n serverless-step-functions

Proposed solution

If the plugin isn’t there, run the command automatically for the user to install the missing plugins.

Closing as it can be considered as addressed with https://github.com/serverless/serverless/pull/9483

For project setup we’re moving from sls create to sls, and when setting up the project with sls dependencies are installed for copied template (released with v2.42.0)

@a-h thanks for clarification, that significantly changes the scope, as sls init is a command we’ve implemented recently which follows up with npm install (if package.json is part of a template).

I take then, this is a request to install missing plugins on sls create (so issue npm install if package.json is there) Note that in Serverless ecosystem it is assumed that plugins are published to npm, and it’s the only package manager that internally is supported by the CLI
