LU-6142 contrib: git plugins

Git plugins to quick see the progress towards
checkpatch cleanups in Lustre.

The original (git-tabcheck) was authored by
Andreas Dilger to help with space to tabs conversion.
The second (git-checkpatch) was modified from
the original script to help capture generic
checkpatch warnings.
