Ensure all lists are surrounded by new lines

See merge request gitlab-org/gitlab-ce!25479

by new lines.

are aligned when they span multipls lines.

Skip user auth check in alerts_controller#notify

Closes #9504

See merge request gitlab-org/gitlab-ee!9636

Do not check if the user can read project in the notify action of the
alerts_controller because that API is hit by alertmanager, and there
will never be a user signed in. Project access will be checked in
the NotifyService which checks if the alertmanager token in the request
matches the token in the DB for the given project.
