Git skip LFS on local repo

Because GitKraken and SourceTree are FUCKING SLOW for repo with large LFS objects.

Need to completely skip LFS operation when pull/fetch/checkout/...

Skip downloading when clone

GIT_LFS_SKIP_SMUDGE=1 git clone SERVER-REPOSITORY

Skip downloading when fetch/checkout/pull
