Allow configuring lfs at the step level

On our CI, we have a lot of different pipeline jobs, some are for testing, some for building, some others for deploying. And it looks like a waste to always pull large file for every of these jobs. In fact, I really need git-lfs only when building my project, neitheir when testing, nor when deploying my already built project. Is it possible to specify support for git-lfs only for some jobs?

Eg:

#!yaml

      - step:
          name: building
          clone:
            lfs: true
          ...
