What does this MR do and why?

This Spike MR explores the 'Temporary branches method' and updates the pull mirror logic to:

  1. Write git data into a temporary branch first, e.g. update-mirror/<branch-name>-tmp.
  2. Sync LFS objects using update-mirror/<branch-name>-tmp branch as the source.
  3. Apply commits from update-mirror/<branch-name>-tmp branch to update-mirror/<branch-name> branch.
  4. Delete update-mirror/<branch-name>-tmp branch.
