Why and how to enable this is covered in the docs being changed
here. This requires gitlab-org/gitlab-shell@2e8b670 ("Add support for
SSH certificate authentication", 2018-06-14) which has been merged in
and tagged as 8.0.0, so GITLAB_SHELL_VERSION needs to be bumped.

Merging this closes gitlab-org/gitlab-ce#34572 see
gitlab-org/gitlab-shell!207 for the gitlab-shell MR.

Implementation notes:

 - The APIs being changed here are all internal, and their sole
   consumer is gitlab-shell.

 - Most of the changed code is a MR to gitlab-shell, see the
   gitlab-org/gitlab-shell!207 MR. That change covers why only some of
   the internal methods get a new "username" parameter, and why some
   others only get a "user_id".

Remove git rake tasks

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.

These tasks are happening through housekeeping right now, by default
ever 10th push. This removes the need for these tasks.

Side note, this removes one of my first contributions to GitLab, as back
than I introduced these tasks through: 54e6c004
