This way we can globally set group only ee events too.
Use nil to indicate global.

allowing override for EE.

This adds an endpoint to get the common ancestor of 2 refs from the API.

System hooks were not being triggered when projects were archived or
unarchived. Reuse the Projects::UpdateService to automatically
trigger system hooks and increase code reuse.

This reverts commit 8717c7da.

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".
