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
