CLI: New command to manage env variables

We’ve shipped a new command for the CLI to manage environment variables.
This feature is 100% community contributed by @Pyrax who did an amazing job:

Docs for the new command can be found here.

To use the new command you’ll need to upgrade to version v2.60.1 or above by running npm install netlify-cli -g.

We marked this command as Beta since it is a new feature and we would like to get some feedback before committing to the API.

You can submit feedback here or in the CLI repo.
