Support distinct environments for different services

[spinlud]

Is there an existing issue for this?

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

Use case description

Something like docker-compose:

serverless-compose.yml

services:
  service-a:
    path: service-a
    environment:
      - FOO='bar'
      - ABC='abc'

  service-b:
    path: service-b
    environment:
      - FOO='whoops'
      - XYZ='xyz'

Would be useful to differentiate environments, especially when using variables with the same name but a different value.

Proposed solution (optional)
