Remove git rake tasks

Closes #41699 and gitaly#768

See merge request gitlab-org/gitlab-ce!20806

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.

Suggestion in:
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20806#note_91261001

This branch includes changes that removes a rake taks that cleans up
config.lock files.

This change bumps Gitaly so it happens automatically so users don't have
to bother.
