This documents LDAP group sync details. When group sync is enabled, non LDAP users will not be removed. They may leave on their own. However, no one can add or remove users manually.

Fix and test leave project display

The 'Leave this project' display on project page was broken. It was calling the method incorrectly, which returned `nil` and displayed nothing. 

This fixes the display and also adds 2 different tests for it.

Sidekiq-cron configuration specific changes for EE

Following the changes at gitlab-org/gitlab-ce!2087, we moved EE specific configurations from `schedule.yml` to `gitlab.yml`, following the discussion at gitlab-org/gitlab-ce#3928

See merge request !78

Sidekiq-cron configuration moved to gitlab.yml

When `sidekiq-cron` was introduced, jobs configuration where placed
in `schedule.yml` file.

As discussed in #3928, this is not desirable. 
We moved it to `gitlab.yml`, exposing only the "cron" part of the configuration.
