Artifacts syntax could look more alike docker-compose syntax

[dgageot]

Skaffold syntax:

artifacts:
- imageName: domain/image
  workspace: ./src
  dockerfilePath: Dockerfile

Docker-compose syntax for the same thing:

services:
- image: domain/image
  context: ./src
  dockerfile: Dockerfile

By using the same syntax, we'd help some developers learn skaffold quicker.

SGTM. We’ll have to think about “dockerfile” in the future if we want to support different “configs”.

I'm going to close this one because it's not really worth the effort
