Resolved Autostart Issue in Wiki

Created by: ZKjellberg

In the installation wiki, there is an issue setting up GitLab to autostart: https://github.com/gitlabhq/gitlabhq/blob/stable/doc/installation.md#3-init-script

It is suggested to setup GitLab for start with the following command: sudo update-rc.d gitlab defaults

The default start number is 20 which results in an autostart before dependent services have started resulting in a failed launch.

Adding the parameter to set the start number to 21 results in a successful boot.

To correct the issue for all new installations, I suggest replacing the above command with: sudo update-rc.d gitlab defaults 21
