Using environment variables to connect via ssh

## Description
This is not an issue but more of a feature request.

I love this tool. I am wondering if it's possible to look into the environment variables when connecting via ssh.

Say you have a `.env` or a `.env.local` with `DB_URL` as a set environment variable that you can ssh into.

I am happy to contribute if possible but would like some feedback on your thoughts. Thanks in advance.
