This reverts merge request !20801

git-lfs 2.5.0 now sets the Content-Type header instead of hard-coding it to
application/octet-stream: https://github.com/git-lfs/git-lfs/pull/3137

To avoid this issue, we explicitly tell the client to use
application/octet-stream.

Closes #49752

Delete todos when users loses target read permissions

See merge request gitlab-org/gitlab-ce!20665

While reviewing this branch it was noted that this task was broken.
Given the limited value this task brings, and given the fact that much
of the old behaviour has been moved to be automatically fixed, removing
was a good option.
