Deploy without repackaging

[tim-helloquickly]

Is there an existing issue for this?

• [X] I have searched existing issues, it hasn't been reported yet

Use case description

There's a serverless package command -- I'd like to avoid needing to re-package in our CI/CD.

Proposed solution (optional)

For me, I wouldn't need no more, but for a more generic solution being able to specify the package name in the serverless-compose.yml file might be a good way.
