Only fetch lfs files for specific git_ref

[Tobias-Fischer]

Description

Currently conda-build fetches all lfs files that ever existed in the history. This is not necessary, and as outlined in https://github.com/conda/conda-build/issues/4809 is costly when e.g. using GitHub. For the specific use case that I have in mind (see https://github.com/RoboStack/ros-humble/pull/155), the lfs files were actually removed from the repository and moved elsewhere (as the GitHub limits were exceeded, and now require payment), but the conda build still fails.

We already have the git_ref that we are interested in, so this is a relatively minor change; much smaller than making git-lfs completely optional as suggested in https://github.com/conda/conda-build/issues/4809

Hi @kenodegard - any chance to run this again, please?

[Tobias-Fischer]

I think this is ready to go - all CI failures are unrelated :)

[Tobias-Fischer]

A quick reminder @kenodegard :)

[kenodegard]

@Tobias-Fischer thanks for checking in, we're still working to resolve the unrelated test failures caused by upstream deprecations, once we untangle that we'll get this moving again
